Re: Shared memory

[Sterling Hughes <st...@bumblebury.com>]

Well, portability is a concern.  mmap() with MAP_ANONYMOUS is the best
way to do shared memory on systems that support it (it automatically
cleans up shared memory for you, and it is just as fast).  But
MAP_ANONYMOUS is not POSIX, iirc its supported on only FreeBSD and Linux
(definitely not Windows).
