Process Data Area:
PROCESSES: 300;
RRA changed this from 200 on June 23, 1986 in response to process exhaustion on an Alpine server when everyone came back from lunch and tried to read their mail. The new PupStream stuff is greedy about processes.
RRA changed this from 150 on January 16, 1985 to be conservative. The cost is small.
State Vectors:
Priority levels 5 and 7 are reserved for the Nucleus. Priority 0 is reserved for the idle process. If you add a (faultable) process at that level, you must also add a state vector for it. Note that a state vector is needed for every process that is running, pre-empted, or faulting (page, frame, ...). Processes waiting for conditions or monitor locks do not need state vectors. RRA pushed up these numbers on January 16, 1985 to be conservative.
