We eventually got it right. It is the default in /bin/sh. It makes
simple shell scripts a lot faster if the programs executed don't do
much work, .e.g. /bin/[, /bin/echo, etc.
The code has to be conditionally compiled to know whether vfork(2) has
shared address space or COW semantics for various reasons.
