   Some boost versions have a bug that can cause a time prior to system boot (or wake from sleep) to throw an exception instead of return timeout See https://github.com/boostorg/thread/issues/308

   Fixes #18227

   I think travis is failing because this catches boost::thread_interrupted and sometimes doesn’t rethrow it. Checking timeToWaitFor <= ::now() prior to calling wait_until might work better?

   That could break in a race (suspend after check, but before wait_until).

   Fixed it by always rethrowing boost::thread_interrupted reliably.
