open(DB_FH, "+<&=$fd") or die "dup $!";
flock (DB_FH, LOCK_SH) or die "flock: $!";
under BSD I get an error when I do this.
Patient: Doctor it hurts when I do this.
Doctor: Well, don't do that.
(is BSD always on top?)
Can anybody tell me why?
My ESP tells me ... wait ... I see an error on line 42 ... no ... wait ...
line 15 ... does "line 15" mean anything to you?
