opening this up for any number of build runs for any number of users
will render a single machine pretty slow, too.

the 2*1800MHz Opteron does it in 35 minutes, if its the only job
running. And that's only if you don't rebuild the documentation.
Imagine you and Yinghai and Ron working at the same time. This will
render the compile time slower than what your laptop is capable of doing
at the moment.

This could be done with a pass-through repository as well. You check
into a devel tree. the devel tree is running an abuild. If it succeeds,
it goes to the stable tree, where hw tests are run. if it works there,
it continues to a "working" tree.
the reason I am talking about trees all the time is that exactly the
move stuff we've been doing recently requires a patch format that
reflects those changes. A check in to a tree is such a diff. We could
also do a branch for each compile run.

one thing, which would also allow a really quick checking on your own
machine (or therefore centrally on linuxbios.org as well) is to drop
romcc. This will get build times per board from several minutes back to
Which in fact would maybe even allow to compile the tree on checkin and
reject the checkin if something breaks.
This could even be done intelligently. If you check something in to
the flashrom utility, no board needs to be rebuilt. If you check
something in to the k8 part, epias dont have to be rebuilt either.
and we're at about 2 minutes per complete compile run.
