Is there a white paper on file locking and how it works, including
techniques of use, particularly dotlocking and flock/fcntl?
I notice procmail 3.15.1 is using dotlocking now to deliver
mail on Linux 2.0.38. For example I can't run a perl script that does a
open (MAIL,"/var/spool/mail/homer");
flock(MAIL,2);
on the mail box and have it work, I gotta do it on the homer.lock file.
It would be helpful to have a deeper understanding of file locking to
better understand the interactions between procmail and qpopper.
