It is the best behaviour? I've seen a couple of emulators which
regulate speed, because it is sometimes necessary for games and
frequently necessary for demos. An additional advantage is that it
reduces the rate at which electricity is converted into heat (ie. it
uses less of the host machine's CPU), so my batteries last longer and
my hands are less toasty. :) And I think it is fair to say that an
emulator which runs at two or three times the original machine's speed
will usually be fast enough. (If speed was really *that* important
you wouldn't be using an emulator.)
