indeed methods (or blocks of code) can be marked "synchronized" which
means theat method aquires a lock before executing. Each object (i.e.
instance of a class) has one lock and each class has a lock. Thus static
synchronized methods aquire the class lock non statics aquire the class
lock. (page 19 of 11may95 lang spec).
