DPS is sweet, but really really costly on memory to run. If you fire up
one instance of cda or dxpsview and play around, your X server grows 
very significantly.

Cheapskates like me who have acquired workstations on university discounts
and now try to use them to support multi-user applications, or tasks better
suited to DECsystems (which are (surprise surprise) not being discounted
nearly so heavily) find Xgrowth is a problem. I run 1 application semi-
continuously that has to be over 15Mb big. if X is getting upto 4Mb big,
and I'm swapping between the two, and the kernel steals 2Mb and I have
a coupla dozen windows/icons open I start to swap. DEC MIPS boxes are fine
but swapping kills anything. The box (3100) takes 24Mb and thats the limit.
I have already blown that away a couple of times (try running dbx over the
15Mb image and xdbx in front of that...)

But to return to context, If I have any complaint about Ultrix 4.2 it's
the need to mung standard X11 clients Imakefiles to get them to compile.
I bet more of us build stuff that needs -I/usr/include/mit than would
have suffered from DEC making the DECplications like dx* have to do
-I/usr/include/DEC-X11 to make cleanly.

I still don't have a finalized site.def and ultrix.def which fixes this.

anyone have one?
