There was a commit by Gary that has fixed the slow slime startup for me.  I think commit 15437 fixed it.

Dex:ccl wade$ ./dx86cl64 
Welcome to Clozure Common Lisp Version 1.9-dev-r15439M-trunk  (DarwinX8664)!

When it does happen, and it may not happen all the time, does not only CPU but also RealMemory go up significantly, e.g., from say 100 MB to a couple of GB and sometime even crash (particularly the 32 bit version)?

Looking at the OS X Activity Monitor shows ccl taking up 100% cpu during swank/slime startup and goes negligible after connecting.  I originally thought it had something to do with Mountain  Lion and me building ccl under that latest Xcode.  I svn'ed the 1.8 release version and it worked fine, I also re-build 1.8 under mountain lion and everything was also fine.
