Exercising pthreads+signals

[Michael ODonnell]

I have a semi-mongrel collection of libraries on a
system that I'm planning to turn over to a client as
a development platform for a coding effort that'll be
making heavy use of pthreads in combination with signals.
We already have some evidence that there might be a
problem here, so I wonder if anybody here happens to know
of a FOSS pkg that makes heavy use of pthreads+signals
that I could use for some shakedown testing.  I'm already
beating on the system with a few pkgs like LTP (Linux
Test Project) and such (yes, I found them using WWW
search engines) and they do exercise much of the
basic pthreads infrastructure but not in the complex
combinations that a genuine app would be likely to do.
The ideal pkg would be structured as multiple cooperating
programs each of which was multi-threaded.

TIA...
