"Source of a problem" is probably a bit too heavy expression :). For
example if I have had a file with lots of undo history, I wouldn't say
it was a source of a problem, but I might decide that I wish to get rid
of the undo history, and start it from clean, without killing the buffer
and opening it a new.

I was trying to reason in terms of a general facility. What do I know
what people use, no idea what can be "throwable" in different modes.
