Good news and bad news.

Good news:

I can confirm that after changing :defer to t, the IDE doesn't crash, 
even after many hundreds of iterations of:

(loop do (let* ((w (ccl::tiny-setup))) (sleep 1) (ccl::send w 'close)))

Menus in the IDE continue to be usable  - I can use the File menu to 
get a new listener, to get a choose-file dialog and open files, etc. I 
can create other tiny windows from a second listener, or other 
creation/destuction loops from a second listener. I even have three of 
these  tiny window creation/destruction loops running at the same time 
with no ill effects.

In short, changing :defer to t makes these cocoa examples that much 
more bullet proof.

Bad news:

If I click the close box of one of these windows, I can get the 
following hang where I'm dropped into the kernel debugger very 
consistently:

Welcome to OpenMCL Version (Beta: Darwin) 0.14.2!
? (require 'cocoa)
COCOA
("FAKE-CFBUNDLE-PATH" "SPLAY-TREE" "NAME-TRANSLATION"

"COCOA")
? (require 'tiny)
TINY
("TINY")
? (loop do (let* ((w (ccl::tiny-setup))) (sleep 1) (ccl::send w 
'close)))

      [ Everything runs smoothly - windows created and destroyed ]
      [ But if I click the close bubble on a window just created…]
