No, you can also type "fg" to let the process continue.

Because sending pthread_kill(SIGSTOP) to a particular thread
apparently has to freeze the entire the process on posix-compliant
systems, and not just the target thread. Early Linuxthreads
implementations did not implement this properly and only stopped the
targeted thread, but this has been fixed in NPTL.
After my post, I google'd some more and found a similar article
explaining the change in Linuxthreads.
There is no portable way to suspend a thread at an arbitrary point
under *nix, see
http://pauillac.inria.fr/~xleroy/linuxthreads/faq.html#E
Okay that makes sense. I guess my Thread Manager did actually teach
me something then. :-) Don't use .Suspend
I'll rework the Thread Manager example. The Java link you sent came
in handle and it explains it very well and shows you what alternative
to use.
Thanks Jonas.
Graeme.
