You could comment out the code in those files that actually does anything
when it's loaded (and the parts that depend on those things having happened
earlier in the loading sequence.) I find that it's almost always faster
to load code that doesn't do anything than it is to load code that does
a lot of expensive things when it's loaded!
Of course, doing those expensive things - initializing the ObjC bridge,
integrating information about declared ObjC classes and methods with what's
actually found by introspecting the ObjC environment and integrating the
results into CLOS - is pretty much the point of loading those files. (There's
always a catch!)
Could those expensive things be made a little less expensive ? Probably.
Significantly less expensive ? Probably not.
Paul's suggestion - saving an image in which that work has been done -
should work, as long as something ensures that the saved image does
some smaller amount of work when it starts up. I -think- that requiring
OBJC-SUPPORT does this, but I don't remember and rarely use Macs these
days, so I'm not sure.
