1. Make a "special" spawnProcess() function for pipe

open.
The last one would let us keep the current API (and would have
the added benefit of cleaning up unused FDs) but I have no idea
how it would impact performance.
How about this: Set FD_CLOEXEC on all pipes just after creation,
but clear the flag for the relevant pipes before exec?
