#4934: threadWaitRead works incorrectly on nonthreaded RTS ------------------------------------------------+-------------------------- Reporter: slyfox | Owner: Type: bug | Status: patch Priority: normal | Milestone: ⊥ Component: Runtime System | Version: 7.0.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Incorrect result at runtime | (amd64) Test Case: | Difficulty: Blocking: | Unknown | Blocked By: | Related Tickets: ------------------------------------------------+-------------------------- Comment (by slyfox): If idea in patches looks fine i can squash last 3 patches in one and cleanup comments around. I can also slightly change polling cycle to resume only descriptors with data available, and not all the waiters. It would be more robust against spurious blocking calls.
