Wow, yes... don't try this at home :p. I did it with a 500-600 line
selection, and it was extreme. After 30 seconds ago the computer also
started swaping heavily, as TM was using over 550MB of real memory
(and a vsize og 1.22GB)... this usage persisted across the undo's I
did to remove my column typing (which went at a more normal pace).
Then, when I wanted to quite TM it went 'busy wheel' for about 5
minutes, still using cpu and still swapping before going away.
Actually... hasn't gone away yet (7 min) :-p.
