(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5) Gecko/2008122011 Iceweasel/3.0.5 (Debian-3.0.5-1)

When having multiple tabs open in both Firefox and Epiphany (both powered by gecko 1.9) I experience system slow down as gecko seems to be hogging a lot of cpu-time calling gettimeofday() (see attachment). A lot of pages are quite evil these days, but gecko shouldn't really tear the system apart even if they are ;)

Reproducible: Always

Steps to Reproduce:
1. Load a gecko powered browser
2. Strace the process
3. Load 5-6 tabs and watch the number of gettimeofday rise..
Actual Results:  
Excessive usage of gettimeofday()

Is this a regression from 2.0 Branch?
