Interchange crashing

Hey all, I am having a problem with interchange - versions 4.7.2 and 4.7.3
will completely crash if the user clicks enough times, making all catalogs
completely unusable. I was unsuccessful at crashing version 4.6 (Akopia demo
1).

At this very moment, I have successfully crashed the demo store for version
4.7.2 (demo 3 at demo.akopia.com). It's still not responding right now, but
you WILL be able to view the first page. I imagine the main page is static,
so it is not affected.

Anyone?
