Today's harvest:

Three likely real problems with patches:

The i7 slave's hard drive started failing, and it's been getting lots
of crashes in the old nvidia driver, so I replaced it and installed
ubuntu-11.10 beta 2.
This exposed a problem between gcc-4.6.1-9 and wine which caused a
reliable test failure in kernel32/thread.ok ( see
http://bugs.winehq.org/show_bug.cgi?id=28640 )
which spewed spurious failure reports until I blacklisted that test.
(Downgrading the slave to gcc-4.5 would do, too, and would probably be
needed on x86_64.)

The most recent spurious error was 3 hours ago,
