There are at least two nasty reasons for LuaSocket's socket.select not
to work well with the file library.

First, on Win32, the select function call can only be used with sockets
(sockets are not even file descriptors). Getting this to work
transparently would require creating threads, which I didn't consider
reasonable.

Even on Unix, Lua uses stream functions (descriptors are not ANSI, I
guess). Although we could use the non-ANSI fileno function (select is
not ANSI either, so who cares?), mixing these things would require
flushing the buffers etc.

If anyone has simple solutions for these issues, please let me know. I'd
me more than happy to adopt it.

Diego.
