Stripped a.out format uses one less block, in general. Fast, simple, less than optimal code generation. More support of read-only files in dos filesystem. Major fixes in permission calculations. Now works pretty much like it was originally described.
Performance tweaks for vstafs.
Allow VM page stealing to be active before swap space is configured. Only stealing of unmodified pages is possible, but this can still be a help on smaller systems. Added shared libraries. RS-232 so you can set parity, data bits, and so forth. Converted all servers to use syslog.
