When pidfile is already locked and has zero length, do not return
...
success and zero pid from pidfile_read(). Return EAGAIN instead. Sleep
up to three times for 5 ms while waiting for pidfile to be written.
mount(8) does the kill(mountpid, SIGHUP). If mountd pidfile is truncated,
that would result in the SIGHUP delivered to the mount' process group
instead of the mountd.

pidfile_close() functions is safe. This possibility is used in example code.
- Cast pid_t to int.

them for reading. When user can open file for reading, he can also
flock(2) it, which can lead to confusions.
