Thanks. There seem to be some similarities between your
`emsane-postop-lisp-operation' class and my task classes. 

Your framework probably fits "around" mine since my concern was not so
much about organizing the execution of multiple specific operations, but
the specifics (like progress indication, cancellation, when and how to
execute) of the execution of a single task (almost same as your
operation).

On the other hand, one could also wrap the execution of an entire
transaction in a task (with progress, cancellation, async execution
etc). This would invert the framework nesting. Maybe they are largely
orthogonal after all.

Kind regards,
Jan
