If you're talking only about KSDC, yes, it was me who implemented
semaphore support a couple of years ago (it has changed quite a bit
since then). As far as I remember, starting from FreeBSD 9.X KSDC
works fine with anonymous semaphores. I had an idea to write an
implementation with named semaphores for 8.X, but never started. Also,
I think that pshared locks were added to FreeBSD, but sysconf feature
line wasn't updated. I'll search my archives.

Anyway, this cannot be the cause of the problems as 9.X and 10.X have
a fully working KSDC.
