A propos locking - how about the flock(2) semantics which are broken in
2.0.27 (LOCK_EX is possible even if the locking process can't write to the
file being locked)? I don't see any patches to the relevant parts of the
kernel source, and this *is* a relevant issue. See also the
denial-of-service attacks against various getties and login programs.
