I guess i should have posted this here before:

That implements the RFC almost completely (there's no much
implementation of the error code thingamajig because actually browsers
don't even implement ping/pong correctly yet!). The implementation is
in pure lisp, but it could be accelerated with a C library (actually
the only thing to accelerate is the xor descrambling, could be done in
an 'in-like environment). The webtest.l in the root of the repo provides
a (ugly) chat server example using my web.l framework. Sorry if the code
is not very elegant but I didn't devote that much time to that example.

Here's the documentation of that module:

Also, the spec is pretty much set in stone, at least as far as the IETF
is concerned, RFC 6455 is a standards track document.
