Per TDPL, having individually synchronized functions is illegal. Either _all_ 
of the functions in a class are synchronized or _none_ of them are. Putting 
synchronized on a function should actually be illegal. It belongs only on 
classes or in synchronized blocks, never on functions.

Now, unfortuntately, I don't believe that the compiler enforces any of that 
right now, so you end up synchronizing indivdual functions rather than whole 
classes, but the synchronized functions themselves should function the same.
