Modified files:
	winsup/cygwin  : ChangeLog exceptions.cc miscfuncs.cc 

Log message:
	* exceptions.cc (_cygtls::handle_SIGCONT): Simplify loop waiting for
	sig_handle_tty_stop to wake up.  Make sure to unlock before calling
	yield to avoid starvation of sig_handle_tty_stop.  Add comments.
	* miscfuncs.cc (yield): Explain why yield should never be called under
	_cygtls::lock conditions.  Call SleepEx with 1ms timeout.  Explain why.
