I noticed that unity-panel-service takes quite much memory. It seems to
be mainly due huge (>1,5 GB) heap size:

pasi@M6600:~$ pmap -X  3184 | grep heap
        00754000 rw-p 00000000  00:00       0 1620100  348264  348264     138388    348264 1271804      0 [heap]

Bug description:
  Impact: high CPU/memory usage from unity-panel-service

  Test case:

  Open a large image in the GIMP and activate a lot of items from the
  global menu. Using shortcuts is enough and faster to reproduce this
  bug (I've always used Ctrl+A and Ctrl+Shift+A). Memory usage of unity-
  panel-service increases steadily and it uses a lot of CPU shortly
  after activating the menu items in a short time.

  Regression potential: check that the menus are stable/working as they
  should

  ---------
  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.
