Weird. I'm running on Kernel 2.6, on Debian, (on PPC, although I've a
only rarely used i386 test server at home with libc6-i686) and I've
not seen any semaphores lock up. Mind you, I converted Exec-Program-Wait
to rlm_exec a while ago, as it's a much cleaner solution to my mind.

Try chaning to using rlm_exec, and if that fixes the problem, then the
issue is near _that_ semaphore, and the best solution may be to either
find out what NPTL's doing differently (signal handling I suspect) and
fix/work-around it, or just deprecate Exec-Program-Wait after 1.0.0.
