I think fixing this may be easy; instead of resurrecting all unreachable
#10241: BlockedIndefinitelyOnMVar thrown to the thread which is not blocked indefinitely -------------------------------------+------------------------------------- Reporter: asukamirai | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 7.8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Incorrect result | (amd64) at runtime | Test Case: Blocked By: | Blocking: Related Tickets: #10793 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): threads at once, we resurrect one from the list, then continue with the scavenge loop. I'll try this once my tree builds. This fix works: Phab:D4644. I'll now try to validate to see if it breaks anything. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10241#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
