WRT 64 bit OS 36MB are ridiculess (and I guess even mt> 36GB are). Sure, I'll try to develop a patch. mt> I never got my hands on Plan 9 but a review in a magazine was mt> rarely talking about these internal things. Plan 9 has an rfork() call that took an argument which is a bitmap of resources to share between parent and child. I believe Linux has something like this. I looked at under the covers and saw the do_fork() in the kernel takes a clone_flags argument which can control fairly precisely what gets duplicated in the child.
