You are not listening very well. Let me say this slowly. Unix V6, V7,
Sys III, Sys V, and 4.1 do not have and useful IPC system for writing
a lock driver with any performance (I suppose you could write out
info to a file, and read it in, but the peformance would be prohibitive).

	I do not now, nor have I ever worked for RTI.
