This sounds useful.  On the PPC this should be used to free memory, I
think.  I don't think this is required for linux, so it is not
implemented yet.

In that case, I assume, all memory should have been free'ed.  If
valgrind would work for grub-emu we could make sure that there are no
memory leaks.

Valgrind does not work because of this bug:

If someone can get some memory tester to work with grub-emu, I will be
very happy.  I did not succeed in getting something to work yet.
