Hello,

I'm about to check in a slew of changes to CCL (OpenMCL) to provide better support for Slime.  I have a version of the swank backend for CCL modified to use the new functionality, and have been using it for a few weeks without problems so I'd like to submit it for inclusion in slime.  However, the swank changes are textually extensive and would be a pain to conditionalize individually, and the versions of ccl without the new stuff are still in common use and probably will be for a few more months.  So the approach I've come up with is as follows:

- Add a new file, "swank-ccl.lisp", which implements the swank backend for ccl using the new functionality.   - Change swank-loader to load swank-ccl rather than swank-openmcl.   - The old file, "swank-openmcl.lisp", still exists, but is not loaded by default.   - swank-ccl.lisp checks whether it's running in a ccl with the new changes, and if not, switches to swank-openmcl.lisp.

Is this acceptable? If not, what would be the best way to proceed?

I've attached swank-ccl.lisp to this message, below is the swank-loader change.
