Yesterday's valgrind results are at http://kegel.com/wine/valgrind/logs/2009-11-16-19.12/
These were done with updated suppressions; see http://code.google.com/p/winezeug/source/list?path=/trunk/valgrind/valgrind-... so don't get too excited about errors going away. (I really should include a histogram of used suppressions so we can know which ones still need fixing.)
I now terminate hung tests (or those that just take too long) with SIGALARM, which shows up as "Command terminated by signal 14". For instance, see the bottom of http://kegel.com/wine/valgrind/logs/2009-11-16-19.12/vg-ole32_marshal.txt
With luck, my automated script will now need no babying, and results will show up 'promptly' five hours after Alexandre commits. (I used to run tests in parallel to reduce that lag; perhaps I'll try doing that again sometime, carefully.)
