fork() should be almost as cheap as vfork() on any system that has a
sane memory manager that does copy on write of the memory.

The linux manpage says there's a few slight differences between vfork()
and fork(), but nothing that should bother nmh.

We don't do any vfork() without an immediately following exec*() call, do we?
