Actually those vendors copied an out of date version of the Symbolics
design, or to look at it from another point of view the Symbolics
design was actively changing while they were copying it, so this didn't
actually produce a common de facto standard after all. None of the PC
Common Lisps I'm aware of have multiple processes, so it's not an
industry-wide de facto standard in any case.

I think it would be a good idea to keep these sort of things out of the
CLIM package, reserving that package for things that are conceptually
part of CLIM and that have been relatively carefully worked out. The
things in the CLIM package should be portable to -all- CLIM implementations
and should be relatively stable.
Having a second package, such as CLIM-SYS, for useful things that happen
to be present in some versions of CLIM seems reasonable, but they shouldn't
be mixed together with the things that are more stable and more widely
