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

I am beginning to wonder if this is different manifestation of the same problem we have. Does it only happen with OS X 10.8/Mountain Lion? 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)?

Can't be at all sure about it but so far there seems to be some correlation between this CPU/Memory surge and creating new threads or not servicing events for some time in the main thread. Never seen this on Snow Leopard or Lion.

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.
