This isn't the place to continue this discussion.  I'll give a brief
reply, but after that, it should probably go to private email.

The server thread is not stuck.  I think you are completely missing the
point (more likely, I am not clearly explaining the point).  The thread
is never invoked until some amount of data was available.

Hmmm.  I think you are mixing too much here.  First, you are assuming
stream-based IO, and synchronous IO implies blocking.  With "record"
based IO (datagrams for IP based stacks), all the data is available, or
none is available.

Again, if you wish to continue, use private email.
