Sorry for the late reply.
I attach the results for maxima, on a machine with 6GB RAM and 4GB swap.
I don't know how to interpret the results. In addition to the test you
requested, when I do this
grep "Committed_AS:" /proc/meminfo
I get this before running maxima:
Committed_AS: 254276 kB
and this after the test finished, before exiting maxima:
Committed_AS: 6878284 kB
I guess this does still not explain why Committed_AS: grows so much
when I'm actually trying to build the Debian package.
Thanks.
