We are constantly running into this issue. The
mem_per_process does help but it is just a heuristic and needs to be tuned quite

The last time this occurred, I did give it some thought. What if we tuned the build
system a little? We could identify the biggest memory hogs and build them sequentially
(post-parallel build?). I know ceph-dencoder was super-memory-expensive (it required more
than 4G of RAM even on 32-bit architectures so we couldn't even build on 32-bit
architectures anymore) and it might be a first candidate on the 'sequential' list.
Do we have any other culprits?
What do you think?
I think this is a great idea. How do we do this in CMake?
