You you have to keep in mind that tests running on a testbot also have a total
timeout of about 2 minutes, if I remember correctly. If a test would be stuck
(for whatever reason), its still useful to run at least the rest of the tests
before the job is forcefully killed. Besides that, the purpose of the tests is
also to verify that the timing works correctly. Apps might rely on that, and
expect the same timing when running with Wine. The tests would be pretty useless
when the tolerance is too big. On my local Windows 7 machines (both on real
hardware and on a KVM based virtual machine) all tests pass very reliable. :/
Does anyone familiar with the testbot setup have any idea?
