slime-autodoc stops working after some time

Hi Orm,

The two key functions at play here are slime-autodoc
(contrib/slime-autodoc.el) on the elisp side and swank:autodoc on the CL
side (contrib/swank-arglists.lisp). For testing, use slime-autodoc-manually
instead of slime-autodoc-space to avoid that ^M. When you reach the point
where slime-autodoc is not working, evaluate slime-autodoc with stepping
enabled (C-u C-M-x). If nothing fishy shows up there, the next place to
look at would be the swank side, then slime-autodoc--async% (elisp) which
is what handles the SWANK reply; you might want to step through that as

Good luck; let us know if you find anything.
