[gambit-list] creating scheme ports from filehandles

Hello
Is there a way to turn a POSIX filehandle into a Gambit scheme port,
or could it be added?
I'm imaging something like:
(posix-fd->port 0) => returning an input-output port
or
(open-port (list posix-fd: 0 direction: 'input)) ;; in case one wants
;; the direction to be preserved.
or similar.
This would allow things like implement functions creating unix
sockets, or maybe even UDP ports; well for the latter maybe more
changes would actually be needed. Maybe I should ask (instead of the
above) how one can, from a C function, read/write from/to a file
descriptor without blocking the system (using the scheduler, thus
possibly running other scheme code in the mean time).
Thanks
Christian.
