Andrey,

thank you for your report:

In principle, I am fine with making that change in Hunchentoot.  I do
wonder what is really going on.  The difference between finish-output
and force-output is, according to the spec, that finish-output
actually waits for the output to have drained, while force-output just
initiates the flushing and returns immediately.  What you seem to
report is that the flushing is not actually terminating when
finish-output is used.  Just to understand what's going on, what kind
of setup did you observe the bad behavior in?  Can you reproduce the
problem and tell us some more about the connections that seem to be
hanging - Are they still in ESTABLISHED or in FIN_WAIT state?

It'd be great if you could supply us with some more information.

Thanks!
Hans
