The discussion is about a new set of fcntl locking commands that are
are respect locks acquired with the old ones but suck less.  This
seems like the right time to discuss what would make them even better.
 The immediate change is to let them be owned by the fd instead of the
process.

This might end up in POSIX and could make sqlite (and lots of other
things') lives easier.
