[slim-vim] ECL Socket callbacks?

[Brad Beveridge]

I just posted this to the ECL list, but thought I'd ask here too.  I'm
hoping Jim might have some ideas :)

Do we need to modify Vim a bit more to support this kind of async
action, or do the current async changes suffice?  If so - what do I
need to do?

Here's what I posted:

Hi all, I think that the question I want to ask is "Does ECL support
something similar to SBCL's sb-sys:add-fd-handler, where code can be
run when data appears on a file descriptor?"

I think this is mostly used to detect incoming data on a socket and
run a handler.
My situation is this:
 - I'm using ECL embedded in Vim (http://wiki.alu.org/Vim_ECL), as
such my Lisp code is not hooked to the main loop, and I don't think I
can use threads
 - I create a socket in Lisp that expects incoming data and I want to
automatically handle that data

Any thoughts on how I can handle this with ECL?

Cheers
Brad
