locking macro broken ?

[guillaume faure]

Hi all. Today, I had to do some thread synchronization and I ended
willing to play with the locking macro, unfortunately, I can't make it
work. Did I miss something ? Looking at the source of MonitorEnterExpr
I think this might be because this expr can be evaluated, but then how
does it works ?

user=> (locking (new Object))
java.lang.VerifyError: (class: clojure/fns/user/fn__1911, method:
invoke signature: ()Ljava/lang/Object;) Unable to pop operand off an
empty stack

Thanks.
