The operating system for the UNIVAC/Sperry/Unisys 1100 series of mainframes
has support `activities' (light weight processes) and multi-processor systems
since the early 1970's.  The OS also did a good job supporting batch,
interactive and realtime applications.  Too bad the file system is totally
brain damaged.
