Dear Kevin, dear Boris,
thanks for your replies. Below is a draft of what could be added to
the Panel doc. I suggest adding it to the first chapter
"Usage" (http://www.mozart-oz.org/documentation/panel/
node1.html#chapter.usage). Any comments?

Add to Panel doc:
Please note that the Panel application itself contributes to thread
and memory usage. For example, whenever the panel display updates the
heap usage (by default, every second when the mouse pointer is over
the panel application) the current heap size increases by a few KB.
Moreover, in the default setting two new threads are created whenever
the mouse is moved anew over the panel, or when tabs are switched
(the number of runnable threads remains 1, though).

Hi Torsten,
The panel indeed consumes memory and it is a good idea to mention
it in
the documentation. We should do the same with threads, because I have
notices that every time you place the mouse over the panel, the system
creates two threads.
By the way, a useful tip for using the panel is to go to Options-
>Update
and then unclick the option "Require Mouse over Panel". Setting the
Update Time to 500ms is also something I usually do.
cheers

Dear all,
I am just studying the memory consumption of some program with the
handy
system panel.
I noticed that whenever the panel is constantly updating (i.e.
when the
mouse pointer is over the Panel's window), the current heap size
increases by about 3 K per second -- even if no other Oz code at
all is
loaded. As soon as the mouse is removed from the panel, the size
stays
where it is. So, this memory consumption is probably caused by the
panel
itself.
I was far a while searching what my program does wrong before I
figured
this out. It is of course totally fine that the panel reports its own
memory consumption, but some hint in the documentation might be
helpful.
Can anyone confirm that this is indeed the case? Would it be OK
then, if
I add a brief remark to the Panel doc (e.g., at
http://www.mozart-oz.org/documentation/panel/
node3.html#chapter.usage.memory)?
Thanks!
Best
Torsten
