Description Andrew Cagney 2007-04-17 16:54:01 UTC 
All ptrace calls must originate from the one thread, and if that thread is the
event-loop thread it can't change.

See frysk.proc.TestBreakpoint for how to rewrite the code and eliminate the problem.

	* TestSyscallSignal.java (setUp): Use Replace EventLoop.run with
	assertRunUntilStop; do not create EventLoopRunner.
	(EventLoopRunner, eventLoop, monitor): Delete.
	(tearDown): Delete.
	(testIt): Replace synchronize blocks with calls to
	assertRunUntilStop.
	(SignalObserver.addedTo, SignalObserver.deletedFrom)
	(SyscallObserver.updateSyscallEnter, SyscallObserver.addedTo)
	(SyscallObserver.deletedFrom): Simplify, call
	EventLoop.requestStop.
