Heartbeat on the average on a real running system should take < 1% or
less of system resources. Dropping that to .9% really doesn't excite me
at all. And, my guess is that it makes the most difference for the CRM
-- which does LOTS more mallocs than anything else (as it must), and
usually does nothing most of the time on a real running system. So, my
guess is that it drops it more like 5% or so rather than 10%.
Andrew has been having some trouble with use-after-frees recently. Our
code catches that -- if it's enabled ;-). If it's disabled, it doesn't
help anything.
