For AJP APR connector 'if (actionCode == ActionCode.ACTION_CLIENT_FLUSH)'
doesn't check if the socket was already virtually closed
so I guess that would be a first thing to look at.
We cannot just check for finished flag thought, cause recycle() would reset that.
Instead if there was getOutputSteam() we would need to directly
invalidate that stream. This means we would need to remember that stream
somewhere.

Further more the wrapped socket is 'long' pointing to the
native pointer, so we don't have object notification on
physical socket close (that's another problem that manifests
in JVM core for detached sockets).

Yes, and a dev list would be better place to discuss that further.
