Assuming those buffers are only used internally and are not intended to
be displayed to the end-user (other than for debugging purposes), then
using buffer names with a leading space should take care of this
(undo is disabled by default in those buffers).
If you're already using a leading space in those buffers's names, then
I wonder how/why their undo was enabled in the first place.
Stefan
