  I had patches for this a while ago.  But they won't apply to the
current code.

  The idea was to update the modsingle struct to have an "elapsed"
entry/array.  Then, call_modsingle() calls gettimeofday() before and
after the call to the module.  It takes the elapsed time, and updates
the modsingle struct.

  After a few more hooks, you can get at the stats via radmin.

  Nope.  Instrumentation is hard.
