Slime frames are either at the top end or the bottom end of the stack.
Those on the bottom shouldn't be a problem.  To hide the frames on the
top Slime needs to guess in which frame the error occurred and that's not
always perfect (ie. it shows too many frames).  Have a look at the
function FIND-TOPFRAME in swank-allegro.lisp.  That's where the decision
is made.  Improvements welcome.

The debugger doesn't change *standard-output*.  The output is probably
in the *inferior-lisp* buffer or the *slime-repl* buffer or you forgot
to call FORCE-OUTPUT.  If you connect to a remote server (or similar)
then the output will be written to whatever *standard-output* is
connected.  You may be interested in the slime-redirect-inferior-output
command which redirects the output which would normally go
to *inferior-lisp* to the *slime-repl* buffer.

It's a bit different in Slime: if you type ",in" you can change the
package.  There a few more of those "shortcuts" and you can add your own
with defslime-repl-shortcut.
