This problem has been driving me nuts. It gets worse over time,
suggesting a leak someplace. Other evidence for a leak, the unity-panel-
service heap grows from 21MB on boot to 350MB or more after a few days
of uptime.

I profiled the system several times using sysprof (see attached
profile). The profiles consistently show that almost all time is spent
in a pair of gobject methods (handlers_find() and handler_lookup()). The
code in these methods traverses a linked list of 'handlers', suggesting
that those lists are growing large.

Some cursory poking around in gdb confirms that the lists being
traversed are very large - at least tens of thousands of elements. I'm
not yet sure why they are growing so big or what's in them.

Bug description:
  Just going about my business on Ubuntu Raring amd64 on an x230 and I
  heard the fan kick into action.  top showed me that unity-panel-
  service was consuming all the free cycles on one of my CPUs.  I killed
  it before my machine overheated, so I didn't attach a debugger to see
  why it was totally pegging out a  CPU.

  I'm not sure if this adds any context, but I was using a LibreOffice
  spreadsheet and I could not insert a table because the menu had lost
  it's mind, and then I observed the overly loaded CPU a very short
  while after that.
