I bought this book hoping it would provide an in-depth tutorial on CLOS. Could she have chosen a worse example for the tutorial (locks)? Why would she choose something that only Lisp machines have and are difficult to reimplement on modern machines?

Very frustrating and disappointing, especially for a language that's so concerned with lasting a long time that the spec is intentionally silent on networking and other essential stuff.

huh? every kernel uses locks to synchronize stuff. -- MarSch 10:14, 21 March 2007 (UTC) reply
