Yep, you're right.  It's not documented very well.  I will make it so.  I
thought about doing this before, but I was afraid to mess up the
serialization stuff.  But, this should work quite well.

I believe that 0 is what the JDK uses in Object.wait(long) for an 
infinite wait. A negative number would also mean infinite.
