I just finished a cvsup/buildworld/installworld cycle and tried
executing a CFLAGS+=-pg compiled version of pkg_info. Except from the
(initially confusing) fact that pkg_info chdir(2)'s into every port's
directory under /var/db/pkg and thus pkg_info.gmon is created in the dir
of the last visited port, gprof didn't segfault or whatever.

However, I now see an artifact, not present previously in my BETA1
world: .mcount seems to be taking the best part of the time percentage
in the flat profile section. FYI I've done a 'pkg_info -a >/dev/null'
and put the output of 'gprof /path/to/profiled/pkg_info pkg_info.gmon'
online at http://ntarmos.dyndns.org/Misc/pkg_info.gprof. I also see this
with my other -pg compiled code, so this is due to either something that
changed between BETA1 and now, or some of the (just rebuilt) libraries
taking up the change in profile.h.
