5649afd028 Revert (once again, and hopefully for the last time) to flock(2) locks.
The problem with fcntl(2) locks is that they are not inherited by child
processes.  This breaks pidfile(3), where the common idiom is to open
and lock the PID file before daemonizing.

8f9085389f Well gag me with a spoon... I'm so used to working at high WARNS levels
that I make stupid fundamental mistakes like this when I don't.

9667055264 I'm tired of seeing this done incorrectly and non-portably, so add a
flopen(3) function which reliably opens and locks a file.
