Unfortunately it is equally possible to put every piece of shareware you
can get hold of on your disk, and then erase it again, and then BOOM.

I did that with my 80 MB disk way back when - the experience caused me
a) to read up on the resource manager internals, b) to look closely at
AppleShare 1.0, c) say "Desktop Manager" to everyone who even suspects
problems with their desktop file. (I still do.)

Including a) the inability to unmount anything which is not a floppy disk,
b) a horrible slowdown (this really is a Finder bug) when you copy 100
LaserWriter fonts onto your HD, everyone of which has the Bundle Bit set. :-(

And Microsoft Word and Excel. :-)
Or how do you think they manage to run their programs in 300 KB of MultiFinder
memory when almost all the program code is in a 320 KB "PCOD" resource?

Incidentally, I assume that Steve Brecher will have a fix out _before_
System 7.0 its the street. :-)
