I have briefly looked at the code, it should be easy to do a straightforward
port.

If I'm correct:
- you need to be able to keep all your data in memory
- disk usage [1] is data snapshot size + commands sequence between snapshots
- it seems that commands should be executed sequentially
- in order to keep [1] under control, you need to take snapshots, snapshots'
cost is proportional to data in memory,
 and while you are taking a snapshot you can't do anything else.

What kind of applications have you in mind?

regards.
