In regress/cmdline, the http-server keeps running indefinitely until
explicitly terminated.  In regress/gotd, nc and http-server exit
on their own after one connection.  My patch only addressed
regress/cmdline and doesn't generalize to regress/gotd.

I thought I'd look how the curl regression suite handles this, as
it fires up all sorts of servers, but that's too much code... both
for me to quickly understand what it does, and to copy that approach.

In practice, timeout(1) is now available across Linux and all BSDs
(Free, Net, Open, Dragonfly), so I guess avoiding it is a pointless
exercise.

I'm still unhappy about
* the use of %1 in a non-interactive shell,
* setting but never resetting a trap that swats at some process,
* exiting on error without terminating the server and relying on
  timeout to kill it.
