Comment 81 for bug 1199877

3.8.6-0ubuntu2 + 13.01.0+13.10.20131031-0ubuntu1, can't reproduce heavy CPU load (thanks!) but I do still see some heap growth. I ran gimp, libreoffice, firefox for 296 seconds and observed:

heap change:
   88 brk() calls, growth of 11496K, or ~38.75K/sec growth

CPU usage:
   4.38% (3.95% user, 0.43 system)

~11 minor page faults/second

So it still seems to be consuming memory quite quickly for me.
