Hmm, can you elaborate on that?

Basically, I *really* want to get away frmo having to use hGetContents.
It is just not at all friendly for an interactive netwrk protocol.  If I
were just streaming a large file from an FTP server, it would be fine,
but even using it to begin with involves using Handles in a nonstandard
way (since there must be a separate Handle for writing, since
hGetContents sents the Handle to be half-closed) that is apparently not
well-supported.
