As noted in bug 848764 comment 10, this is expected. This measure is
counting the decompressed library memory twice because there are now
two different views of it mapped simultaneously, while there was only
one before. Measuring PSS instead of RSS would show no regression,
although it would have other problems (influence of other processes on
memory usage)
