I will also try that in the next session.

One problem I have here is that since I run this session I have not
get any problem. My uptime is over 2 days, I have not changed my
habbits of work within Emacs and my swap remains under 200 MB and only
10% memory used by Emacs, normally 80-90%

Almost by the rule I could not run longer than 1 day until I would get
swap of about 3 GB - 4 GB and not responsive Emacs.

Can it be that libmtrace.so could prevent something happening what is
normally happening?
