(1) For the situation where large processes fork and immediately exec,
many other *IX system have a "vfork" system call to handle the situation.
(2) The claims that statically that this is okay 99.9% is hogwash. The
airline industry may sell tickets that way, but they don't want their
computers doing it. I've been in line when it has happened to them and
its not a pretty site.
(3) This is sure a time waster for porting and developing programs to run
on Linux. "Hey, you know that program that worked fine on System A could
blow up on Linux." This is espcially true for those people who want
to move binaries from some other vendor's OS.
