Description Andrew Cagney 2007-04-17 16:52:16 UTC 
All ptrace calls must originate from the one thread, and if that thread is the
event-loop thread it can't change.

Comment 1 Andrew Cagney 2007-04-17 16:55:22 UTC 
See frysk.proc.TestBreakpoint for how to rewrite the code and eliminate the problem.

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