As has been mentioned before, the (kernel) semaphore implementation
in -current doesn't work well. In pkgsrc Python, use of semaphores
was disabled because threaded Python scripts didn't work. I also found
that disabling semaphore use in gcc/libgomp fixes crashes of programs
using OMP (eg darktable).
It worked with userland semaphores until NetBSD-6, so I'd wait for
a resolution before burning bridges.

best regards
Matthias
