[CM] CM question re: CFFI

[Rick Taube]

dave -- are you using  sbcl or cmu? rts doesnt work in cmu since cmu 
doesnt doesnt have pthread support.
it hopefully works in sbcl modulo the problems with portmidi 
interaction (see the rts topic help about that)

cmio shouldnt need rts -- but maybe there is a problem with dependancy 
in that code now that ive made rts a seperate system.
