On a related note, in 2002 Russ said he'd implemented, then commented out, an mmap implementation for Plan 9. See /n/sources/contrib/rsc/linuxemu/linuxemu.c for the code. To make it work in user-space you'd need user-controlled process creation (which we've discussed on this list before) along with some extensions to segattach functionality. Given the 'joys' of mmap over remote file systems, we *really* don't want it in Plan 9 as-is! --Joel
