On Windows, waiting on system timers is notoriously inaccurate, with short sleeps taking tens of milliseconds longer than specified. This led to these tests to sporadically fail on the Windows GHAs with `check 5 == counter has failed [5 != 4]`, because it couldn't get the expected five invokations within the given tolerance of 50ms. Currently on master, the tests check if a timer triggers five times in 550ms with a 100ms interval, only leaving those 50ms to spare. This commit extends the tolerance of to 75ms. This is a pretty conservative increase (when we could have gone to 99ms), but it might be enough to satisfy the windows GHAs.
