Okay, but 626 and 577 seem to address the issue of being blocked in a "wait" when \
attempting to establish a connection.  From what I gather from the code and trace \
below, the connection is already established and these threads appear to be blocked \
in a "read" from clients.  How are these related?

Thanks.
