Hi,
I think I came across a (possibly) new bug in SLIME, here is the description:

SLIME: cvs snapshot 24/04/2010
Emacs: 23.1.1
SBCL: 1.0.37   
ITERATE: 1.4.3
system: Linux Fedora Core 12 x86 32bit

Description: the following code
;-------%<-------%<-------%<-------%<
(require :iterate)
(use-package :iterate)
;-------%<-------%<-------%<-------%<
evalueted in either inferior-lisp or slime-repl causes slime to "hang", i.e. after the use command the repl prompt stays unresponsive, I tried waiting several minutes.
Commands like slime-interrupt and slime-quit-lisp don't work either, I have to manually kill the sbcl process to quit lisp. Both emacs and sbcl are alive and waiting, in fact it does seem the computer is just waiting me to give some input.
The same code evaluated without using iterate's package or inside a unix terminal works without a glitch.   

TIA

Andrea
