Z:gnu-www-ja-rms-lisp--304fc6-The one exception was redispla/en

The one exception was redisplay. For a long time, redisplay was sort of an alternate world. The editor would enter the world of redisplay and things would go on with very special data structures that were not safe for garbage collection, not safe for interruption, and you couldn't run any Lisp programs during that. We've changed that since &mdash; it's now possible to run Lisp code during redisplay. It's quite a convenient thing.
