First, list display need not be involved. For example:
set $len = Flength (which_symbols (Qnil, $my_limit))
pp $len
These GDB commands print a count of how many symbols have
the value nil, while not bothering to count any symbols more than
an upper bound of $my_limit. On a 64-bit host, there's no good
reason for these commands to misbehave merely because $my_limit
exceeds 2**32.
Second, even if display is involved, it is sometimes reasonable to
ask for the display of a long list. For example, when debugging
Emacs under GDB, I sometimes generate long outputs which I then
analyze with other tools.
