Summary:                    Exceptionally long queue length queuing to XXXXX
Description: 
Although this is under test conditions, this can go on for ever - seems
like 100's per second.

But the state of code at the moment, allows you to hangup, and it clears.

That deadlock, although under 'testing' conditions, potentially could
happen at any time, it's just a matter of time. We need to at least get it
documented.

For the record, my machine isn't a core2duo:
Intel(R) Pentium(R) 4 CPU 2.60GHz (hyper threading enabled)
Memtotal: 2068264

When were getting the "Exceptionally long queue", the CPU is at 188%
The it goes back to normal, no deadlocks.

But many open channels: where they would have normally been optimized
out.
