Try using psyco and see if that helps.  Also, sometimes smaller blocks are
better than large blocks.  Try using smaller block sizes and see if that
helps.

If you're worried about the time required to calculate the length of your
block, try calculating it once and pass the length around.  Is that doable?

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.
