Good job ! It had a bug wich is corrected in today's cvs patch.
But I didn't find a trace of the :: delimiter. Maybe you should check ?
and : together, and not : alone. I don't know how you imagine this in
your head, but go ahead and code as you like :)

One thing, it isn't more CPU-intensive than the old version, as both
make my CPU (1000MHz) between 0 and 2 at idle. I'll test both on a
133MHz notebook, and write here when finished :)

I had a 'freeze' at first launch, dunno if this was a segfault (it
 didn't reproduce), but this new code runs  now good for 2 hours.

There's no memory leak at first sight (in fact, I check with top :) not
 very professional)

Err... don't drink too much, or you'll want to call v0.10.0 the "Feisty
Dunnart" version (think about kernel 2.6.2 :) ====> [] )
