[Openmcl-devel] Read all available input from socket stream?

Greetings all.

I am attempting to read all currently available data from a stream. I am 
not expecting much data, so I suspect I need to call finish-output.  
(read) seems to return immediately, before it seems that data is 
available.  I guess in hindsight I don't know how the implementation is 
supposed to know when input has stopped coming in on what is 
conceptually a stream with no eof representing any termination of input.

I guess what I'm saying is, given a socket stream, is there a way to 
read, blocking until there is input to be read and until there is no 
more data to be read, this kind of stream?

this is a paste of the funciton I'm trying to get working.  I want to 
write something to the stream, and I expect something back, which I want 
to either return from this function or simply emit to *terminal-io*
