We resolved this and two followup issues on IM; all localized issues.
Thanks again for the help!

I've attached two refreshed patches including the relevant fixes, and
the addition of a 'user_data' pointer to events; as desired by Thomas.

I plan to push these after some msvc animals turned green. We might want
to iterate on the API in some parts, but this will fix the regression,
and imo looks good.
