Raul, I'm afraid it is a problem for us mere mortals.  This thread got
started with a problem associated with XVision, an X server product
for MS Windows.  It's a good product, but recently I tried to use it
to access TeleUse - an interactive Motif development tool that we
have in on evaluation.  My Compaq has 8Mb real memory and a 3Mb
permanent swap file.  Before starting Teleuse, the W3 program manager
says that 67% system resources are free.  Once Teleuse starts, I'm 
down to 1% free, and the whole system grinds to a halt.  The problem 
appears to be that TeleUse uses icons like they're going out of fashion,
and has very complex screens, so XVision has to ask a lot from MS Windows
in the way of resources.  Obviously, Windows 3.0 doesn't seem up to the 
job, and I'm worried if these limits are not going to be addressed in
3.1.

Today, TeleUse might be thought of as an unusually hungry program,
tomorrow it will probably thought of as typical and Windows programs
themselves will be wanting the same scale of resources...
