We too see resource consumption on this level (only larger). Bjam
consumes 3.4 Gb memory to analyze dependencies (our project is C/C++/

We're using Boost Build from 1.38 at the moment. You can see some of
our OS and compiler configurations by looking at the Sandia results
on the trunk testing page (the 3.4 Gb result above is on Linux RH4
with gcc-4.2.4). I'd love to be a beta tester for a python port, if
you're looking for testers.
