Comment(by pcapriotti):
Updated win32 patch so that it falls back to `GetTickCount` (with a 64-bit
accumulator). Using `GetTickCount` should be perfectly safe, since it's
impossible to delay more than 2^31 μs (less than 6 hours), because
`threadDelay` takes an `Int`.
Incidentally, `GetTickCount` also seems unaffected by changes in the
system clock, so the only difference would be in accuracy.
