Please only add tests that are really acting random and cannot be simply fixed.
Updating the list
Testman fetches the current version from the SVN repo. To update the blacklist, checkout testman from svn://svn.reactos.org/web/trunk/www/www.reactos.org/drupal/sites/all/modules/reactos/testman/, locate and update blacklist.txt and commit.
- ntdll:info - number of tests/failures depends on the number of running processes which may vary between runs
- urlmon:url - (Alex: is wildly random/erratic, I believe due to ws2_32:sock)
- user32:msg - random possibly due to TrackMouseEvent
- user32:win - number of tests/failures is quite random
