I'm betting only 4 times as fast (maybe 5). Just because you've quad'd
the clock (internally) doesn't mean you see a 400% increase in total
response. Besides when you load the next version of WinX it'll boot
about as fast as my Atari 800 off the disk. :-)

Still I wonder how many emulators can one run under another? I know
I've done Linux -> DOS -> CP/M, Linux -> Linux doesn't count (self-
referencing variables ;-).
