No. It can produce pure C code (unregistered), but to get high
performance it processes the output assembly afterwards (registered).

You might be able to. Much easier would be to use Yhc and pass the
--dotnet flag which generates .NET binaries natively.

There isn't going to be much free/delete, its all a garbage collected heap.
