firefox in 8.1-RELEASE: High CPU consumption?

I'm observing what I think a high CPU usage with the "www/firefox" port
Even with a blank page loaded (about:blank) I see CPU loads around 7-9%.
I've done a truss on the browser and I see what appears to be a loop and
some "timeout" and "resource temporarily unavailable" results on calls
to "read". I'm attaching a gzipped file with the result of truss.
I'd appreciate if you could shed some light on this.

When running firefox (3.6.4).
* How to reproduce the problem:
Launch firefox and go to "about:blank". Run truss against the process.
I can always reproduce this problem.
