DEADLOCK_WAIT

   DEADLOCK_WAIT defines the number of seconds that a lock request
   must wait before the system initiates a deadlock search on behalf
   of that lock. Setting DEADLOCK_WAIT to zero disables deadlock
   checking. Setting DEADLOCK_WAIT to a value greater than zero
   and less than the default setting provides faster detection of
   deadlocks but requires more CPU usage.

   The DEADLOCK_WAIT value is expressed in seconds; therefore, the
   smallest value you can set is 1 second. Beginning in VSI OpenVMS
   Version 8.3, a subsecond deadlock wait time, which is set in
   the system service $SET_PROCESS_PROPERTIESW item code $PPROP$C_
   DEADLOCK_WAIT, overrides DEADLOCK_WAIT. For more information, see
   the $SET_PROCESS_PROPERTIESW system service in VSI OpenVMS System
   Services Reference Manual.

   DEADLOCK_WAIT is a DYNAMIC parameter.
