> There's a bunch of severe rendering problems that stem from the
> TxnProgressWidget periodically polling its backend data source at fixed
> intervals, regardless of whether the previous fetch is actually done.
> Now that we have post-processors for fetchTxnProgress.php (buried deep within
> AMBARI-249), this has become even more severe because our post-processing
> script potentially triggers background jobs (that should run just once) more
> than once, so this needs to be fixed ASAP.
