Okay, next question, what does this default to? (Please, oh please,
   don't say 0.)

pretty sure it is 0....
   
   I guess I could just read the source, but, um, doesn't this kind of
   information *belong* in the section 2 man page? Default belongs in
   section 8 in addition to the priority description...
   
   (Yes, I'll do a send-pr with the man page patches.)

yes, it probably does belong there (as well as in section 8).
