FWIW, checkout of these things took 5+hrs, staying on the local
.freebsd.org net w/o hitting the 'net at all.
As promised,
$ time cvs ci
real 67m51.701s
user 0m1.250s
sys 0m5.345s
something already there (PORTOBJFORMAT, OSVERSION) or move stuff from after
.include <bsd.port.mk> to before.
(This is not by any means the complete list but just the ones I've noticed
recently.)
