Ok, I think it's a plan then. I have a partial implementation for
guest-file-* commands on windows, and a posix/w32 guest-exec-async
implementation that re-uses them, so maybe those should be introduced
around the new interfaces to avoid churn. Need to generate uuid handles
for guest-exec handles anyway.
