    8 CL:RANDOM uses a better random number generator (r13327).  When calling (make-random-state t), 
    9 the lisp will initialize the random state object by reading /dev/random if it is available (r13333).  Windows ports 
    10 use a quasi-documented library function to do a similar thing (r13334). 
     8== Background processes in the Cocoa IDE == 
    119 
     10As of r12416 in the trunk, CCL supports "background listener processes" in the IDE. 
     11 
     12{{{ 
     13(gui:background-process-run-function name thunk) 
     14}}} 
     15 
     16executes the 0-argument function THUNK in a lisp process named NAME with the standard stream variables effectively bound to a stream which references a listener window (with associated Hemlock buffer and infrastructure.)  The window is invisible (it's actually created on demand) unless/until an I/O operation is performed on this stream. 
     17 
     18When the process is runing, the window's close button (and CMD-W/the Close menu item) hides the window but doesn't deallocate its resources or kill the process; subsequent I/O operations to the stream cause the window to become visible again. 
     19 
     20If a background listener window is visible when the associated process exits, it stays visible (so that its contents can be saved - via "Save To ..." - or otherwise manipulated.) 
     21 
     22 
     23When the window is visible and the process is in a break loop, they behave like other listener windows/processes: the backtrace and restarts dialogs can be used, and the listener window/process can be used to evaluate selections from editor windows when the listener window is the frontmost listener window.
