in a source code file buffer
C-x 2
M-7 C-x ^
C-x o
M-x slime
C-x o
eval some wrong code
press zero to close the debug window
the second window size is back to where it was before shrinking it

Maybe that's not a usual way to work for more experienced slimers. It also
happen with elisp evaluation by the way. When the mini-buffer
auto-completion window pop-up, it sometimes resize the second window, if
it's too small I think, but restores window configuration afterward. I find
this much less annoying. I didn't thought about looking at how it's made for
auto-completion, just remembered that detail today.

Slime is quite a beast, it must not be easy to maintain with lispers of all
kind as users! While I'm still using just a fraction of it's power, I
already think it's the best development environment ever.

Didn't knew about all this, that explain why the slime-set-emacs-snapshot
function isn't being used. I've had a look at winner-mode and I'll certainly
use it. But I think it doesn't really resolve this issue, as we still have
to type 'C-c left' (I'm very lazy ;-).
