Other tuning sources are welcome too.

Eh, normal make variables can go in src.conf as well.  They do not have
to be listed in bsd.own.mk.  World builds include /etc/src.conf whereas
every make invocation includes /etc/make.conf via sys.mk.  The only reason
to use /etc/src.conf is to have a place to put variables only affect
make buildworld / buildkernel but do not affect other make invocations.

Also, MALLOC_PRODUCTION is generally enabled in a stable branch as part of
making the stable branch, there should be no need to set it manually in a 
stable branch.
