You could try doing it the hard way.  In a loop, sleep for 1-5 seconds at
a time.  Everytime you complete a sleep, check the elapsed time.  If the
elapsed time is >= the total sleep duration, fall out of the sleep loop
and try your email again.  This should allow your service to stop within
1-5 seconds of your request while imposing little to no load on the system.
