It "should" timeout, yes (I don't know the expected timeout duration), but I also didn't write binkit/binkp.js, so I'd have to track down that bit of code and see what its doing to be sure.

The SBBS event thread is a single thread. BinkIt polling is normally done as a timed event, which is run as in the foreground of that single event thread. So I'm not clear what "another thread" would be.
