[slime-devel] Restartable frames

[Terje Norderhaug]

Six swank back-ends implement the RESTART-FRAME interface. Yet only  
two of these back-ends implements FRAME-RESTARTABLE-P, which is used  
by the BACKTRACE slimefun to identify whether a frame is restartable.

Allegro and SBCL implement both restart-frame and frame-restartable- 
p. ABCL, CCL, CLISP and LispWorks only implement restart-frame.

For consistency, perhaps back-ends that implement restart-frame also  
could implement frame-restartable-p?
