Right, or if you wanted to guarantee your garbage software would get
installed, and you get the money from the spamware it also installed. So
people will do anything to get more cash.

So I believe. Some people will even vote (your least favourite political party
here) ;)
Some people are scum.

Hahahaha.
It's a *game*. Many use 100% CPU no matter what you're doing or how fast
your computer is.

True. So does Access 97, BTW...

Well, it makes sense: At some point it costs more to produce the device
than its selling value is, it doesn't make any sense to produce it anymore.

Also, if the mahjong program was created with a GC'd language, the GC
might completely nullify the benefit of swapping.

Only if the GC actually runs.
If the program isn't "doing anything", it shouldn't need to run the GC
either. Typically the GC is set to run only when no more objects can be
allocated. (Altough sometimes they're set to run when idle as well...)
Of course, if the GC doesn't work properly...

I think Warp might mean that the program might tend to hold onto data longer
than it really needs to, in the event the GC doesn't run. Since a GC sweep
by an otherwise mostly-idle program would only bring stuff into core once,
so it wouldn't nullify the benefits of swapping it out.
However, many GCed languages will take messages like iconification and
priority lowerings and do a GC before going quiescent. In this case, you
might even get better behavior than in a language where you can't compress
used memory because people are holding raw pointers.
Windows already trims your working set and swaps much of your program out if
you're idle and the window gets iconified, as well.

Oh come on, don't start yet another pro-GC flamewar.
(just today I had the pleasure of reading the old thread "the POV-ray
SDL--similar to Java and/or Python?" in p.advanced-users)
