With the upcoming multi-core CPUs the need for sane SMP support will
increase, I think.
When it would be possible to let the maintainer define if a package builts
fine on SMP systems with -j...

Erm, well, some m68ks already suffering from bad disk i/o (macs). Concurrent
builds might slow down the builds as well due to higher memory requirements.
For Amigas there're not that many accel cards that support >128M RAM... I
don't know how fast the disk i/o on ataris or macs is, but on my Amigas it's
<5 MB/s even with the new kernel patches from Kars... and using two buildds
with c++ builds on the same machine will result in much swapping for sure...
