/**************************************************************************
Verification of INKqa06643

Schedule a continuation that is simply called back with a later timeout
value. Explicitly call INKContSchedule() without a mutex, the mutex should
be created in InkAPI.cc/INKContSchedule. 

This plug-in will not complete the client request (request times-out), 
since the event routine calls INKContSchedule() in the event handler.  
A simple change to the event routine can be made so that INKHttpTxnReenable() 
is called in place of INKContSchedule().

Entry points to the core now use either 
	FORCE_PLUGIN_MUTEX 
or
	new_ProxyMutex() 

to create/init a mutex.
