Bug Description

When hud-service is running, my desktop load looks like this:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
8222 vorlon 20 0 1937m 874m 20m R 102 23.3 263:06.78 firefox
5148 vorlon 20 0 1146m 449m 7288 S 41 12.0 24:25.24 unity-panel-ser
3306 vorlon 20 0 757m 326m 3444 S 21 8.7 0:15.26 hud-service

If I kill hud-service, after a while firefox settles down and it looks more like this:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
8222 vorlon 20 0 1927m 872m 21m S 10 23.2 263:59.29 firefox
4777 root 20 0 269m 61m 17m S 3 1.7 33:41.11 Xorg

While the CPU is pegged, the firefox UI is unresponsive.

This seems to be correlated with whether I have a form loaded in one of my firefox tabs, but I haven't confirmed that definitively yet.

I am using Unity 2D, if that matters.

After a discussion with Chris on IRC, I've trimmed my bookmark menu, getting rid of an old, autocreated "Bookmarks Toolbar" subtree. After restarting firefox (without which my submenus were not populating at *all* anymore), the problem has not reoccurred.

So this may simply be the bookmark menu problem after all.
