Most of the tests in a configure script don't actually have to run in 
series.

Writing the code to analyze all the tests and build a dependency graph 
would be pretty tricky, though.  Getting portable shells to launch N 
tests in parallel (where N is probably cores * 1.5 or so) at a time and 
integrate the results would be even trickier.  You could do it easier 
in, say, Erlang, but then you've thrown portability out the window.
