> In the original implementation of the program, 'pid monsters' could be killed not only by the program's user, but also by other 'pid monsters' and normal Doom monsters on the level. The reasoning behind this behavior was that "on very heavily-loaded machines, it is not uncommon for the OS to kill random processes." Unfortunately, the number of monsters in a given area must be depressingly small in order for them to avoid both intentional infighting and friendly fire. Since monsters would tend to kill each other off until only a few remained in the area, the user was severely hampered in the ability to orderly control processes on the machine. Therefore, the default behavior of psDooM is to ensure the player is the only character in the game who can wound and kill 'pid monsters'. This avoids accidental process deaths from monster infighting. Unfortunately, it doesn't prevent accidental process deaths from a user's poor aim. ;-} The original behavior of 'pid monsters' being as vunerable as other monsters may be enabled with a command line flag. That's amazing lol
