{ PREEMPTIVE_REASON: (input)  This indicates the type of signal and flag
{       preemption that is desired.  The valid values are TMC$WAIT and
{       TMC$LONG_TERM_WAIT.  TMC$WAIT will allow any preemptive signals and
{       flags that interrupt PMP$WAIT to be disposed of.  TMC$LONG_TERM_WAIT
{       will allow any preemptive signals and flags that interrupt
{       PMP$LONG_TERM_WAIT to be disposed of.  If any other preemptive value is
{       supplied this request does nothing.
