> The newly added thread safety tests (and possibly some of the existing ones) 
> tend to run for a long time, consuming a lot of CPU cycles, and sometimes 
> even failing due to a timeout (currently 300 seconds in nightly builds). It 
> would be useful to provide a mechanism such as a command line option whereby 
> the tests' runtime could be limited without necessarily causing them to fail 
> when the amount of time is exceeded. One way to do it would be for each test 
> to set an alarm in response to this command line option and in handler for 
> the alarm set a flag that each thread would check at each iteration of its 
> loop to see if it should break.
