[Mono-dev] NancyFX self hosting (HttpListener) locking up on linux

[Greg Young]

This has been going on for almost nine months look in list for "tcp issues"
which is why I'm curious that patch may not fix. It has with significant
(thousands of hours of testing) fixed problem for us. What os etc is being
run.

We have frankly also been surprised that this reported behaviour almost a
year ago is apparently considered not very important.
