It didn't even work correctly for BCPL programs!  Sure, it worked
somewhat, but the Resident command allocated more space than it
should have - including a data segment that should be allocated on
startup, not when the program was installed as resident.

Even a _little_ more thought would have been nice ... like checksumming
the segments to see if they had changed - if so, allocate space for
new ones - in other words, take what you can and replace the dirty
segments from the disk.  I'm not flaming you guys, I'm flaming MCC.

Hey, speaking of the Toolkit (well, you did but I trimmed out that part),
what can you say about the program to allow overscanning?  It's mentioned
in the 1.2 release notes (poof) but the gamma 1 toolkit doesn't have it
and the 1.2 release toolkit isn't out yet.

Are you still in Los Gatos or have you returned to West Chester?
