   2  * This is where the lock files are kept.  It MUST be on the same
   3  * file system as the "mailboxes" directory.  It also must be read/
   4  * write by the world.  When a mailbox needs locking (while being
   5  * read and cleared by inc, or written by deliver), a link to the
   6  * mailbox is made in this directory, under the same name (i.e., the
   7  * users name).  Links are one of the few things even a privileged
   8  * process (deliver) cannot over-ride.  The deliver process waits
   9  * for lockwait seconds for the lock to clear, then it over-rides
  10  * the lock.  This number should be set around 15-30 seconds in the
  11  * case of a VERY loaded system.
