In addition to this (I also add "ulimit -t 3600" to my pbulk.conf)
there are some packages that simply hang without using CPU, and
there's no reasonable way to detect this.

For these, which include textproc/ja-groff, I have this section in my
mk.conf that skips such packages entirely:

You will probably want similar.  Some of these packages may have since
been fixed, though, so we should verify the full list at some point.
