Preemption is superflous for VDUs.
The user is notified through the VDU header area and
a bell each time a FLASH message is queued for the
VDU. As the user has the capability to cancel/suspend
the transaction in progress himself and to request
the presentation of the FLASH message CR suggest to
remove the preemption requirement for VDUs.
The user is anyway always capable of avoiding a preemption
by initially specifying a message under preparation
to have the precedence FLASH and as the last thing
during preparation insert the right precedence.
