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

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.
