Given that the eCos file handling model is almost identical to that of
Linux, BSD and any other Unix variant, I would expect that they would
all behave in much the same way.

You might be able to do something fancy using select() in place of the
recv(). Signalling a select()ing thread should work -- although that
is essentially just the same as the cyg_thread_release() you are
already doing.
