Thanks a lot Michael for the detailed reply.

@You : "...No, I don't expect that it will be feasible to do this..."

Ok. I understand. No problem.

@You : "...It might be possible to set up something that would trigger an exception and then you'd get the crash dialog which has a save option on it..."

Perfect! This could be sufficient :)

@You : "...But an already existing way would be to use the regular Sweep command for doing this, it should be interruptable unlike the Pipe command..."

Thanks for the tip.

But, besides the benchmark and "pipe" or any other command I simply wanted to talk about the problem of "non interruptable" things and "lost work" because of forced closing of Moi.

Anyway, thanks a lot for your support.
