Specifically, it apparently makes no attempt to handle overflow when computing expiration times. Namely, `GHC.Event.TimerManager.registerTimeout` has: {{{#!hs now <- getMonotonicTimeNSec let expTime = fromIntegral us * 1000 + now }}} Even worse, we currently throw away the delay requested by the user, meaning it is no longer possible to account for overflow after registration. This can be fixed, but will require a bit more allocation in timeout registration. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15158#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
