Dear Haskellers,

I am baffled by a strange bug (?) with threadDelay on Windows. It delays for less time than expected (500 seconds vs expected 24 hours), and is consistently reproducible on my system. Can someone have a look (need some patience, ~8 minutes waiting), just to be sure? I glanced around trac but didn't find any related issues.

I believe I fixed this bug a few weeks ago. Indeed there was an integer overflow in then non-threaded Windows RTS. This should be fixed in GHC 8.2. See Trac #7325. Cheers, - Ben
