Overview
Comment:Revise results of the thread-7.28 through thread-7.31 tests to account for the fact they are canceled via a script sent to the thread asynchronously, which then impacts the error message handling. Attempt to manually drain the event queue for the main thread after joining the test thread to make sure no stray events are processed at the wrong time on the main thread. Revise all the synchronization and comparison semantics related to the thread id and error message.

	* tests/thread.test: Remove unnecessary [after] calls from the thread
	tests.  Make error message matching more robust for tests that may
	have built-in race conditions.  Test thread-7.26 must first unset all
	thread testing related variables.








2011-11-18  Joe Mistachkin  <[email protected]>

	* tests/thread.test: Remove all use of thread::release from the thread
	7.x tests, replacing it with a script that can easily cause "stuck"
	threads to self-destruct for those test cases that require it.  Also,
	make the error message handling far more robust by keeping track of
