> An issue exists where Pass Through transport Pipe goes into a dead lock situation during
pipe error scenarios. A situation arises where the Producer and Consumer threads wait on each
other. This reproducible with high concurrent burst loads using pass through transport and
can lead to all PTT threads being locked causing synapse HTTP to be unresponsive. 
> I've attached a diff (created over trunk) that addresses this issue for your consideration.
