[postmodern-devel] [Sbcl-devel] Possible bug in REFILL-INPUT-BUFFER

I know. The situation that we want to avoid is CL-postgres calling
read on a socket that has unflushed data -- then both the server and
the client will wait forever. Thus, it is enough to call force-output,
which ensures that the flushing is initiated, and the next read won't
block forever.

Best,
