----------------------------------
Attachment: 0001-QPID-6213-Fix-misuse-of-Timer-in-queue-cleaning-code.patch
don't think my fix would schedule the next purge whilst one was currently
happening unless the purge took long enough that it was longer than the between
cleaning interval.
Is it really the case that purging the queues can take longer than the 10
minutes between purges?
I attach a slightly better behaved change, which will continuously push of the
next queue cleaner trigger as the purges are happening - in this case a single
purge would have to take longer than the cleaner interval.
Note that .restart() has the effect of pushing off any timer firing by the
timer interval *from now* so if you continually call restart then the timer
will never fire. This is how heartbeat processing in the broker works - by
continually pushing off the processing of the heatbeat timeout.

> The broker misses heartbeats and connections get timed out.
