    It looks like this change was already made and the comment is

I just compared the latest CVS version of describe-function-1 with the one
in my build, and there is no difference. To me, that means that the problem
still exists.

The problem might not be at that comment, actually. It looks like the
complete set of keys is computed, and then it is simply not all printed if
the number is too great. That saves printing space, but not time (not much).

The list of keys should not be completely computed in the first place - just
computed up to some reasonable limit. (And perhaps let programs bind that
limit as a variable?)

There is no noticeable delay even for commands bound to a few dozen keys,
but self-insert-command is bound to zillions of them. It is essentially a
special case that needs to be treated as such, or else, as I say, the list
of keys should be computed only up to some limit.
