I was thinking about autotools and ./configure itself.
For end user ./configure itself is more important (more ofen used).

Ok,
maybe turn ./configure more SMP will be easier?
What about split ./configure to n files
(n=2 for dualcore)
./configure ==> ./configure1 + ./configure2
and then
/bin/sh ./configure1 &
/bin/sh ./configure2 &
or
in ./configure
odd commands run normally
and even with &
Autoconf / configure is quite forky and expensive, but is worth the

I was checking my cores load, and the second one has a lot of idle, when
./configure goes.
