[Bug 230993] [NEW] completely unkillable process eating 100% CPU

Public bug reported:

In Hardy, it seems that sometimes certain processes will go awry and
become completely unkillable, i.e. kill -9 has no effect.  When this
happens the processes appear to be consuming 100% CPU.

I am reporting this as a kernel bug because kill -9 should basically
always work, regardless of a bug in a particular program.

The most frequent program to encounter this issue seems to be totem, as
reported here: http://ubuntuforums.org/showthread.php?t=788380

I have, however, also seen Firefox do this, specifically when playing a
movie with Flash.

This issue is definitely new in hardy.  I have been running the same
media-center computer under edgy, feisty, and gutsy, and I've never seen
this issue before.
