* Fix issue with long wait for passed timer [bugfix]
This fixes a small issue where a timer that had been completed while
code executed would still wait for more events before being considered
completed. This would in some scenarios incur a 500ms delay to the
completion of a timer.
* Refactor logic into
* Add test case based on original issue
* Use longer timeouts to be more lenient in checking
* Revert to short timeouts, but widen the accepted range
* Widen accepted range further, it is meant to check for a 500ms delay after all
* Increase poll timeout to make it easier to detect mistakes
