I've got a really trivial [sketch](http://paste.stevelosh.com/570d778c67478a00075f46c2?lisp).\r\n\r\nWhen I run this under the homebrew-installed CCL with `/usr/local/bin/ccl64` I get 60 frames per second, as expected.  When I run the exact same code under Roswell's CCL with `ros run -L ccl-bin` I get 30 frames per second.  Performance drops further for the Roswell version as I add more circles.\r\n\r\nBoth the homebrew CCL and Roswell CCL appear to be the same version of CCL (`Welcome to Clozure Common Lisp Version 1.11-r16635  (DarwinX8664)!`).  What could be causing the massive drop in performance when running through Roswell?"}}
