Shared system routines

[Andrew Klossner]

	"The idea precedes VMS; DEC's RSTS/E for the PDP-11 has had
	`Run-Time Systems' for some time.  They essentially allow
	re-entrant code to be accessed by any number of jobs at once."

And the idea precedes RSTS.  TOPS-10, the PDP-10 operating system upon
whose architecture RSTS was based ("hey, let's write TOPS-10 in Basic
for a minicomputer!") implemented "Object Time Systems", which occupied
the upper half of the logical address space of a program written in
Fortran, Algol, or Cobol.
