When I've made a few calls, I get spikes on my cpu graph (applet in
gnome-pannel) around the time png/qng show up in the logs, and top says it's
butterfly that's responsible. Attaching a profiler to a running program is
kinda tricky though, if you don't want to get your figures distorted by the
activities that happen before the problem arrises.

It probably won't become a massive issue ever, because when you time-average
it, the spikes only take up <5% of my computing power. 

It's probably going to be something really subtle like accidentally triggering
a full garbage collection sweep. If you're not up for investigating it, I'll
understand.
