1 03/05/85  Hardcore Wait Event Identifiers
 2 
 3 The ring-0 wait/notify protocol requires that a 36-bit identifier be
 4 supplied to indicate the event of interest.  When a process waits,
 5 this event identifier is specified by the process that notices that
 6 the event has occurred (i.e., the process that notifies the event).
 7 This info segment contains a description of all wait identifiers in
 8 use by the system, with a brief description of each.  The identifiers
 9 are given in octal, with ASCII interpretations where appropriate.
