Re: buffer transactions (was Re: Very interesting analysis of "the state of Emacs")

[Richard M Stallman]

    Just an idle thought... has anyone considered transactional support
    for buffer modification in emacs? This would enable simultaneous
    access to buffers by different processes/threads and (it seems) could
    be implemented by changing the insert primitives in scope for a
    background process to record a transaction log of all the changes a it
    wants to make to a buffer (or variable for that matter) and merging it
    with the state of the actual buffer on completion of the process.

We should just make `atomic-change-group' bind a variable to
temporarily prevent thread switches.  That would do the job
and would be much simpler.
