Hi,
Attached is a patch which defines and implements (for SBCL and CMUCL) a basic profiling interface for SLIME.
Profiling submenu and following key combos added: C-c p {t,u,f,r,c}
The CMUCL implementation is not tested, since my swank-cmucl.lisp does not compile currently, but it is written according to docs. If somebody with working CMUCL SLIME could have a look, that would be fine :)
Cheers, Michael
