If a user tries to use MAIL from two different jobs at the same time,
the second MAIL dies with the message "?Invalid simultaneous access".
The MAIL.CPY file is being written by both jobs, and only the first
job can win.
Make the user wait if the file is busy. In the OPENF of the file,
set the OF%AWT bit to cause waiting until the file frees up.
