	* testsuite/libjava.lang/TLtest.java: Reduce sleep time.
	* testsuite/libjava.lang/Thread_Alive.java: Remove old email address.
	Reduce sleep time.
	* testsuite/libjava.lang/Thread_HoldsLock.java: Modify to work around
	compiler bug.
	* testsuite/libjava.lang/Thread_Interrupt.java: Remove old email
	address. Reduce sleep times. Synchronize with target threads before
	attempting to interrupt them. Don't try to calibrate yeild count,
	instead, always loop for a fixed time.
	* testsuite/libjava.lang/Thread_Join.java: Remove old email address.
	* testsuite/libjava.lang/Thread_Monitor.java: Likewise.
	* testsuite/libjava.lang/Thread_Wait.java: Likewise.

	* testsuite/libjava.lang/Thread_Wait_Interrupt.java: Likewise.
	* testsuite/libjava.lang/pr179.java: Likewise.
	* testsuite/libjava.lang/Thread_Sleep.java: Likewise. Reduce sleep
	time. Remove upper bounds check on sleep time.
