Any help is always appreciated ;-).
I will probably not modify the current socket code for 2.1.7.
However, 2.1.7 will contain a way to see C type as first class Scheme objects.
Using it, I was able to write a new extension, called "posix" which implement
posix functions in STk. Not all POSIX.1 functions are yet implemented but it
would be easy to extend it (any volounteer?). Select is not (yet) in it since
it is not POSIX.1, but I will probaly add it.

Send works in STk as in Tcl/Tk after you have to set the X authentication
mechanism in place. The only problem with send, is that the result is always a
string (i.e.
        (send "Another_STk" '(+ 1 2))
returns "3" and not 3). I hope to make things better some day...
