Judging by the symptoms, you have built a version with what we now call
--disable-spinlocks; that is, it didn't figure out how to do assembly
TAS on your platform and fell back to using SysV semaphores for spinlocks.
Quite aside from the drain on semaphores, the performance is going to
be spectacularly bad, so you'd better fix that.
