 There's a rumor that sometimes GetTickCount64 or GetTickCount can move
 backwards.  This is possibly due to a misunderstanding of bug #23558
 (fixed with `77cc97cf0a20ed0a062a1cb87bef6c40941e4cff`).  But in case it
 isn't, we should fix it.

 (QueryPerformanceCounter *can* move backwards, and we have code to handle
 that.)

 Putting this ticket in tor:unspecified since I don't actually think we
 have a bug here.
