I suspect the performance of Virtual Acorn would be pretty bloody nasty
when used inside something like VMware or Parallels, as neither provide
any support for the graphics acceleration that Virtual Acorn uses.

There's also an issue with the VM's JIT cache: JITing JITed code never
results in good performance, as it's a pain to cache.
