Bug #7141: puppetd runs fail in 'daemon' mode when stat'ing /proc files

I accidentally had a tree that Puppet was watching (auditing) with a few files
that pointed to the /proc filesystem. Manual puppet runs worked perfectly, but
background 'daemon' runs would hang. After a bit of stracing, I found that the
hang started as soon as the puppet process tried to look at these /proc
symlinked files. Again, manual puppet runs worked perfectly, but the daemon
background runs are the ones that failed. Removing the symlinks solves the
problem, but this is a bug of some kind.. I'm just not sure where.
