The Forth way ;-)
No, really. It does not make QEmu too slow to be usable, but it takes
very, very much from the performance improvements QEmu has in comparison
to bochs. Just try the interpreter patch, which is very good to have a
regression test, but otherwise is just slow as compared to FAST!
Ciao,
