No, it isn't.  Calling an escape procedure from call/cc is as fast in
Chicken as calling a "normal" procedure (which is to say somewhat slower
than in comparable Schemes like Gambit), so Oleg Kiselyov's portable
implementation works well.  There are only a few Chicken-specific touches,
as you can see by loading the code with "chicken-install -r F-operator".
