Yep. Look at System.Threading.ReaderWriterLock.

As you are already doing just start stripping out the complexity until the
problem goes away. Then try to build a simple app with a similar construct
that apparently caused the problem.

Yes, that's what I was asking. Is the event handler code sufficiently
compact that you can post the snippet?

It appears that we are NOT receiving the (completion port) callback from
an asynchronous socket (BeginSend/EndSend) call.
The sockets are clients and the failure seems to be related to shutdowns
on the socket.
This has the effect of leaving a pinned GCHandle on the heap (pinning the
send buffer).
