not really "overloading"

I operate the other OpenBSD buildfarm member (spoonbill), if you are
running the buildfarm script under a user that falls into the "default"
login-class (/etc/login.conf) it will get a limit of 64 maxfiles and 64
processes.
This limit is too small for make check to complete - so either up the
limits for the default login class or move the buildfarm user to another
class with higher limits.

beside that one of my other buildfarm boxes (lionfish) happily works
with 48MB of RAM - so 64MB is plenty enough ;-)
