* socket.io application object & request wrapper
*
* The first few requests when hitting the site will be pre-cached, as the socket won't
* have had time to connect yet. Socket.io already does this, but we want to fallback to
* AJAX instead of waiting however long for a socket to become available. If there's no
* response from the socket server in a given time then AJAX will be run to load the initial
* page content instead.
*
* This kind of mechanism should respond better under high load (if/when open socket connections
* limits start to become a problem). It also allows us to easily disable the socket server
* if we're experiencing any unforseen load issues.

* Sub-class specialization of EventHandler base class.
*
* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
* scheduled asynchroneously, avoiding recursive calls in the same tick.
*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
* and cancelled with `clearNextTick`.
*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

* Sub-class specialization of EventHandler base class.
*
* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
* scheduled asynchroneously, avoiding recursive calls in the same tick.
*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
* and cancelled with `clearNextTick`.
*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).
