["as Win32 does not have" should have been read as "as Postgres Win32 does not have"] I'll have a look at how we could fit in spinlock code for Win32, or at least, using the Win32 semaphores. (Do you have any idea on the historical context of this code? I wondered as to, if we have no win32 port, why there would be a seemingly good-to-go sema replacement?) No chance on getting the Shmem bootrap rearrangement past you, as described in my earlier mail? IMNSHO, it is not entirely without merit.
