Let me clarify.  What I meant by "blocking" on open() is the blocking
affected by the Berkeley O_NDELAY flag.  open() will always wait for
access to the inode (or vnode).  O_NDELAY only affects opening tty
devices and FIFOs.  (In the Berkeley derivatives I'm familiar with).

(Is it time to change the Subject: yet?)
