Yeah, I'm hoping to get it added at some point, but have been
distracted by other projects recently so haven't finished it up yet.

You might try building SBCL from CVS, there were some bugs with
callbacks on win32 fixed since 1.0 that sounded like they might be hit

I've seen that also (with Linux SBCL), I assume they worked for
