Dawrin- why does pinky SIGBUS (was: What to do with 'make check'?)

Well, for starters...

Honestly I have never used pinky so I don't really care. (WAG: 
print_entry is missing a check for NULL?) I'll take a look at some of 
the others with ktrace (hmm, why does the test that wants strace not 
know about ktrace?).
