[hobbit] bbgen using full CPU

[Josh Luthman]

Anna,

I forgot to mention that once this bbgen test kicks into gear, it never
reports anything.  On the main view it is green, but on details of the page
it is purple - and stays that way.

Henrik,

In case it is relevant the core was put in /home/shire/data/acks - not the
usual ~hobbit/server/tmp

It is reproducable - I can kill the ps and restart hobbit, every single time
I start hobbit a few seconds later the CPU is overrun with this one PID.

Here is the gdb output:

Is this what you need?
