replying to myself in the same thread, I wanted to inform everyone that after
upgrading to Mageia Linux Cauldron (the Mageia development branch that is going
to become Mageia 3), the problem has worsened. Now, mount.ntfs sometimes
consumes over 50% of CPU (27%-60%), and gam_server consumes 20%. I don't get
anything of this sort with Nautilus.

I think I'll report this problem to the Mageia bug tracker, and see if anyone
can shed any light on it.
