Yes, that's true.  They wrote the original ASPN recipe with the basic 
threading trick.  But I ran into a few nasty problems along the way (after 
rewriting that ASPN code completely, just keeping the core trick), and Antoon 
and John were the ones who fixed my hangups (and John got all the WX Timer 
stuff working).  All in all, the best of open source, collaborative effort: 
none of us was an expert at this, but bit by bit we pieced together a working

Sure, pass me the patch.  Hopefully John, or someone else, can take a stab at 
this at so the pygtk stuff works as well.  I'll give it a try myself, but 
since I've never used pygtk, I'm quite likely to miss even obvious stuff.>

Anyway, this will be _very_ good to have in working order, and I think it will 
be something that many people even beyond the scipy crowd will benefit from.
