Perhaps you could try the patches posted here and report whether they
reduce/increase memory usage? I am afraid that at the moment there is none with
enough free time to work on this, so all the help we can get is appreciated.
If you want me, i can close the other bug as a duplicate of this to have all
info in a single bug, and update the description mentioning also memory usage.
