I know I'd seen something like this before, thanks for reminding me.
There are several issues with PearColator/RVM:
- It's written in java. qemu is written in C, so a lot of porting would be
required to get anything working.
- The best benchmark results are half the speed of qemu, and ten times slower
appears to be a more typical result.
- I can't see an any way of doing an incremental transition. My code generator
coexists with dyngen, allowing a gentle migration away from dyngen.
