Base class for all wait-able condition objects. WaitConditions are used in a yield statement inside tasklets body for specifying what event(s) it should wait for in order to receive control once more.

Abstract base class, do not call directly
Prepare the wait condition to receive events.
When a wait condition receives the event it is waiting for, it
should call the method
L{wait_condition_fired<Tasklet.wait_condition_fired>} of the
tasklet with the wait condition as argument. The method
returns True or False; if it returns True, it means the
WaitCondition object must "rearm" itself (continue to monitor
events), otherwise it should disarm.
@param tasklet: the tasklet instance the wait condition is
to be associated with.
@note: this method normally should not be called directly
by the programmer.
Stop the wait condition from receiving events. @note: this method normally should not be called by the programmer.
