Flaky test update

Here's some data over 1042 test runs over the last
three weeks, all on a dual core Ubuntu 8.04 linux box with
a cheap nVidia GeForce 8500 GT graphics card.

Three tests crashed from 1% to 10% of the time (as opposed to failed):
ddraw 136
d3d9   48
d3d8  12

Three tests always failed:

urlmon:protocol.c 1042
dsound:ds3d8.c 1042
dsound:ds3d.c 1042

Two tests usually failed:

user32:msg.c 940
user32:input.c 756

Nine tests failed from 0.1% to 20% of the time.
(Even tests that only fail once in a thousand runs
are bad, since they cause spurious patch failure reports.
I've blacklisted all the tests listed here, which means
patchwatcher *ignores* these tests, even if they have
valid failures.)

comctl32:tooltips.c 206
user32:win.c 205
riched20:editor.c 174
kernel32:thread.c 124
wininet:http.c 59
ddraw:visual.c 7
advapi32:service.c 7
kernel32:debugger.c 2
urlmon:url.c 1

Of those nine test, the following six had a fairly small number of
characteristic error messages:
And here are those error messages:
