It may be reasonable to expect fcntl() to work correctly, but it's
not necessarily true that you're going to *get* it. Witness this
note in the RELEASE_NOTES file from the sendmail distribution:
Revert to using flock() whenever possible -- there are just
too many bugs in fcntl() locking, particularly over
NFS, that cause sendmail to fail in perverse ways.
Also, perhaps I missed it in this discussion, but just what *is*
the security problem WRT having /var/mail set to 1777?
