Inevitably, when you're testing in your own, private environment,
everything works great. You test test test and are finally convinced
that it's all perfect. Seconds after you merge it into the main SVN
trunk, you find a dozen little mistakes. Sigh. :-\
After a bunch of SVN commits, I think I have all the mallopt fixes on
the SVN trunk. Please test as much as you can. We should let this
soak on the trunk for a day or three before moving it to the v1.3
branch (CMR already filed).
