stream-fd only makes sense with serve-event. Then, why not storing the defgeneric _there_? That a generic function is related to gray streams does not mean that it has to be in the file src/clos/streams.lsp Besides this, I would add the call to the generic function stream-file-descriptor at the end of stream-fd as a last resort, and preceded by a #+clos-streams This way serve-event still relies on a function (stream-fd) that may or may not have this clos-related extension.<br>

</div>Sure but where exactly and how? If I sustain the old definition of<br>
stream-fd in serve-event.lisp, there's an Once And Only Once violation<br>
between that stream-fd and stream-file-descriptor in clos/streams.lsp.<br>
<br>
So probably stream-file-descriptor would have to be based on stream-fd;<br>
in what file should I place stream-fd?<br>
