We have some pretty poor error reporting for interrupted $where's and map reduces. We should fix the interruption bit and accumulate stack's across threads
Something like:
Turn:
I QUERY [thread4] js thread raised js exception: JSInterpreterFailure Error: error: { "$err" : "Unknown Failure from JSInterpreter", "code" : 8 } :
