    What I don't understand is what prevents two initiators from continuously

    aborting each other's I/Os?  Consider the following:

What prevents this is quality devices.  CHECK CONDITIONS are not usual
At least with disk drives, you are very unlikely to ever see the situationn
CHECK CONDITIONS all the time screwing up two devices.  If you see that,
then there is something fundamentally wrong at the target side (e.g. the
device is NOT READY), and nothing you do at the SCSI interface will help
one way or the other.
