This is really good!

The stacks containing "MessageLoopForUI" are the Chrome user interface
thread that communicates with X etc.  But in all cases they seem to be
stuck in a stack topped by __sys_poll inside glib.

Chrome attempts to only call into glib when glib won't block, but it
appears to be blocking in glib.
There's a bunch of rather subtle logic in this code:

I guess some of it is somehow wrong.  :(
