(gui::background-process-run-function 'foo1 (lambda () (print "I'm dead")))

(gui::background-process-run-function 'foo2 (lambda () (loop (sleep 1))))

Executing the above two forms causes the expected results: a second Listener that says "I'm dead".

However, if you close that Listener window, the window comes back when you hit cmd-L (even though its process is dead). Windows attached to dead Listener processes should be deleted completely once closed.

The toplevel :cd command differs from typical system shell usage in that quotes are required around the directory name. This can create quite a lot of stumbling for a new user, making the command seem broken. This could be alleviated by changing the :? HELP entry for the cd command to:

(:CD DIR) Change to directory DIR. Quotes are required, i.e. (:cd "..")

CLHS is clear about it "2.3.1 Numbers as Tokens", the syntax for
floating point numbers is:

    float          ::=  [sign]
                       {decimal-digit}*
                       decimal-point
                       {decimal-digit}+
                       [exponent]  
                        | 
                       [sign]
                       {decimal-digit}+
                       [decimal-point
                           {decimal-digit}*]
                       exponent    
    exponent       ::=  exponent-marker
                       [sign]
                       {digit}+    

that is, at least one decimal digit is required before or after the dot.

With no digit, the token +.e2 should be read as a symbol.
