I don't much like the idea of changing something like popen, though I confess I can't think of anything that your suggestion would break. But let me take this opportunity to push one of my pet causes: the under-use of FIOCLEX, which causes an open file to be closed after a successful exec() call. For one thing, it closes a security hole (does *your* version of Adventure close the cave file during a shell escape); also, it prevents problems with programs running out of file descriptor slots.
