A minor clarification: the symbol CCL:MAKE-READ-WRITE-LOCK is exported
and the function it names is documented. It creates a lock which can
be locked by multiple simultaneous readers or by a single writer.
It's probably not the best choice here for your producer/consumers situation
(though you -could- probably make it work.)
However you handled locking, David's suggestion about using a semaphore
is good advice.
