        Various rlimits are set to very small values by default, such
        as maxproc=128, descriptors=128, and datasize=256M; or at
        least, I see these defaults on my 2-core i386 with 2 GB RAM and
        my 12-core amd64 with 32 GB RAM -- I'm not sure exactly where
        they're set.  It would be nice if these scaled with the
        available RAM or something.


        Try ` -j12 distribution' on a machine with 12 cores and
        32 GB RAM.  Watch it fail on vfork when enough subprocesses
        have been started.


        Yes, please!
