Reproducible: Always

Steps to Reproduce:
1. copy the xul code from http://pastebin.mozilla.org/573298 into your XUL explorer.
2. click the "click me" button.
3. The ff ui then freezes with memory footprint increases and increases (as seen from the Vista's Task Manager)

2. the memory footprint keeps increasing and increasing (until i have ff killed)

Expected Results:  
The background thread should work itself silently without affecting the UI's response.
