Thanks Ben.
I have a question. Would it make sense to have a setting to reset on
each session the registry?

Naively I'd presume it must always do this to cover:

* the OS upgrading libraries

* moving images between OS platforms and dropping the old platform's FFI in memory

* moving images between flavours of Linux where libraries are in different locations

* moving images between 64bit & 32bit VMs (or wait! I forget if thats possible?)

What are the use cases where you would *not* reset the FFI registry each session?��

What you should know is that Guille is actively improving
(refactoring, rethinking the API of iceberg) to produce a better UI then.
We are really concerned how we can get the same confort than we got before.
