Mono's tracing facility to see how often the methods I mentioned in my
last email were being called and in what order. And if that doesn't
work, instrument the class libs themselves.

It's probably in the sockets code, so take a diff of
System.Net.Sockets.Socket between 1.2 and 1.2.3 and see what, if
anything changed. If you can narrow it down to a specific change
between the releases, that will hopefully make it easier to write a
