Further reduce the number of semaphores used under --disable-spinlocks. Per discussion, there doesn't seem to be much value in having NUM_SPINLOCK_SEMAPHORES set to 1024: under any scenario where you are running more than a few backends concurrently, you really had better have a real spinlock implementation if you want tolerable performance. And 1024 semaphores is a sizable fraction of the system-wide SysV semaphore limit on many platforms. Therefore, reduce this setting's default value to 128 to make it less likely to cause out-of-semaphores problems.
