That sounds like something we'd like to see officially merged so please
provide your patches!

Why? That sounds more like a supicious bug or something.

That seems likely, yes. A broken TCP connection is potentially a really high
price to pay when you multiplex N streams over that connection, but also when
using multiplexing such a connection should also be kept alive at basically
all costs. Don't kill your client processes if you want them to keep
connections alive!
