Public bug reported:
Hi, my Firefox browser randomly lock up when consuming 100% CPU (1 full
core on 2 cores) and writing on disk at 3 to 5MB/s (according to iotop).
attached is a backtrace print by attaching gdb during a lockup.
I have several of these, including from firefox 13.
Looking at the gdb output I also see lot of thread creation/destruction.
