Another possibility is to just use SysV semaphores instead of POSIX semaphores. Then you can use the ipcs(1) command to manually cleanup. BerkeleyDB uses SysV shared memory when you specify a shared memory environment and it appears that SysV semaphore support is actually more widespread than POSIX semaphores.

Just to mention that at least on HPUX, Posix semaphores are more efficient than SysV ones.

I'm also reminded that there is no defined behavior for SysV semaphores in threads, they are only speciried for inter-process synchronization. So forget that...
