Yes, I'm perfectly aware of the potential problem.  It would be up to
the admin to not run anything that might hang or delay for a long
time.  Is the DHCP server supposed to protect the admin from shooting
himself in the foot?

What if the execution were made completely asynchronous?  The child
process could daemonize itself before calling exec(), and the parent
server would not need to wait() for it.

What OS facilities is the dhcp code allowed to require?
