In general, I recommend MX_MAXIMUM be about the amount of RAM in your
system divided by 20MB.  So on a 512MB system, an MX_MAXMIMUM of 26 or so
should be safe.  If you usually have more than MX_MINIMUM slaves running,
then bump MX_MINIMUM up to a couple more than the "usual" number of
active slaves.

Absolutely.  That will help a lot.  Also, 2.34's queueing feature might
help (I can understand why you want to wait for 2.35.)
