Valgrind cleanup status

[Dan Kegel]

The logs of valgrind errors at http://kegel.com/wine/valgrind/logs/
are showing a nice downward trend:

The spike at 11-27 was when I started running with
my heap tail corruption detection patch; those errors
were present before, but not detected.

Thanks to everyone who's been chipping away at these
warnings.   (Part of the decline has been knowing which
suppressions to add, but that's ok, cleaner logs are good.)

I'm mostly worried about nonleak errors for now, so
I might be undercounting leak errors somewhat.

As always, more help with these would be welcome.
Some of the errors aren't that hard to deal with
(but at the same time, some of them look easy but
are subtle, so take care).
