[Openmcl-devel] Slow Slime Startup with 1.9 dev OS X

I updated my 1.9 devel branch a few days ago and now the time to start ccl under slime is quite large.  Sometimes greater than 30 secs (and a few times I had to abort slime connection).  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.

Version with slow behaviour

Dex:ccl wade$ ./dx86cl64 
Welcome to Clozure Common Lisp Version 1.9-dev-r15382M-trunk  (DarwinX8664)!

1.8 version

Dex:ccl18 wade$ ./dx86cl64 
Welcome to Clozure Common Lisp Version 1.8-r15436M  (DarwinX8664)!

Is anyone else having the issue?
