Comment(by andrea):

 I'll amend that; flock is just advisory locking by default.  The fcntl(2)
 man page makes it sound like you can get the Windows-like mandatory
 locking behavior on Linux by mounting the filesystem with -o mand, though.
 This could probably be tested with its datadir on a loopback-mounted
 filesystem with that option and flock.
