    Think of a big log, and then a kbd macro that removes things between the
    lines that match a regexp (similar to what `occur' does).  Some of the
    chunks removed were probably more than 1MB.

A kbd macro (or function) that does a lot of work could indeed produce
a big undo entry.  This is exactly the sort of case this feature is
protecting against.
