    A few years ago, I worked on an Apollo and used csh.  After a
    while, someone showed me a way to tell csh to disable job
    control, which significantly sped up job execution.

    Can someone out there refresh my memory on what this command
    is?

You set the environment variable INPROCESS to "true".  But it won't
buy you as much now as it did in the good old days, when vfork was
much slower than it is now.  Personally, I wouldn't bother.  You
run into other problems running inprocess.  It's not worth it.
At sr10, it's a no-op, since most everything runs extra-process.

The one exception is if you run a csh directly from process 1
(the boot shell).  It won't work if you aren't running inprocess,
because the streams don't get connected right.  But you shouldn't
ever have to do this.

    Also, while I'm at it, does anyone have a program for changing
    the color map on the fly?  I wrote one once, but it had a bad
    habit of crashing the system.

I have one, but unfortunately don't have the source for it.  I
think I can send it if you really want.
