I think the issue is that src/include/port/linux.h does not believe that
PARISC knows about test-and-set, so you're getting extra semaphores
being created (or trying to be created) to substitute for TAS spinlocks.
This is bad for performance, quite aside from the fact that you'd need
to boost the system's SEMMNI and/or SEMMNS to run Postgres that way.

Feel free to send in a patch that fixes it ;-). There is code already
that implements TAS for PARISC under HPUX, but I'm not sure whether it'd
need any tweaking to make it compile under Linux.
