Sorry, changes I did to code at last moment were not correct. This is 
what I had before and was correct:


The node.checkNotEntered() must be called before synchronized block, 
since it contains a check for Thread.holdsLock(). node.enter() does not 
contain a check, so checkNotEntered() must be called before synchronized 
blocks that call-back user code too (where necessary).

Regards, Peter
