Heikki Linnakangas daf3d99d2b Add comment to explain why PGReserveSemaphores() is called early
Before commit e25626677f, PGReserveSemaphores() had to be called
before SpinlockSemaInit() because spinlocks were implemented using
semaphores on some platforms (--disable-spinlocks). Add a comment
explaining that.
