One thing to consider: why not call javaInstance() on LispObjects to
obtain the lock object, instead of using the LispObject itself?
Pros: JavaObjects would be unwrapped and thus it could be possible to
share a lock with Java code. javaInstance() returns the LispObject
itself in most other cases.
Cons: "most" other cases is not good enough. E.g. for Fixnums, it is
possible if I understand it correctly that two subsequent calls to
javaInstance() will yield two different Integer instances and this is
Maybe instead of always calling javaInstance(), you could test for
JavaObjects and call it only in that case.
