I also use  "urxvt"  with a scrollbar  and a buffer size  of 3000 lines.
But neither is this guaranteed to be enough, nor does it help when work-
ing directly from a console  (except perhaps when your kernel has Alan's
scrolling patch applied).

Well, I tested this using "most"  from within a "urxvt" terminal, and at
least with default options  it did not work for me.   No output was dis-
played at all and even "^C" did not work.   I had to explicitly kill the
"emerge" process  from another  terminal window,  and only then received
the output from "most". :-(

I also tried good ol' "more" and "pg", but even though they both accept-
ed "^C" they somehow interfered with the question "emerge" should final-
ly be asking.  I did not yet test all these pagers directly from a cons-
ole, because I'd prefer a universal solution for this problem.  And come
to think of it, I'd prefer a solution with "more" or "pg" because where-
as "less" and "most"  each are provided  by packages  of their own,  the
former two are both provided by package  "sys-apps/util-linux"  which is
even installed on my live USB stick, if I remember correctly.

Sincerely,
  Rainer
