If the 'stuck builds' were getting stuck because of autoconf 'conftest'
programs getting stuck in a loop and never exiting, I had the same from
my build of ~1mo ago - I did not get to the point of investigating
the real problems, but running a little loop to kill conftest processes
in another terminal let my build proceed without manual intervention.

I'll probably retry another build in another jail at some point not
too long from now and try to track down the specific tests -
but in any event, some of the problem packages for me then were:

drwxr-xr-x  1 root  wheel  0 Sep 25 01:38 wget-1.14
drwxr-xr-x  1 root  wheel  0 Sep 25 02:13 freeciv-share-2.3.2nb1
drwxr-xr-x  1 root  wheel  0 Sep 26 03:39 coreutils-8.13nb4

Attached my kill script - probably a more elegant way to to this,
esp since it determines the stuck process from the last modified
pkgsrc work directory and so it would not be -J compatible, but
perhaps it's useful.
