Description of problem:

I think it is a good feature to add the option for using parallele
decompression for installing the distribution and rpms
if Mageia detects a machine with more cores.

The parallele decompression / compression tools maybe activated
in normal use (Ark / Fileroller) because they are compatible to their pendants (example pbzip2 / bzip2)

Please report whether this bug is still valid for Mageia 2.

Thanks :)

rpm doesn't support that thus we cannot do it.
