I will resist this mightily. One of the main reasons to switch to mmap
was so we would no longer have to explain about SysV shm configuration.
Are we going to still have to explain that, but only for FreeBSD?
No thanks. It will certainly not be the *first* resort. Instead,
somebody needs to hold the FreeBSD folks' feet to the fire about when
we can expect to see a fix from their side.
