Why would you not let another thread do this nasty kind of polling and let the main loop check for a changed result, if at all?

  Close, on a synthetic fd with no I/O performed, should not take 100ms per call. This is a Linux performance bug.

    close can take arbitrarily long, it's a blocking operation. Don't ever call close on the hot path.
