If you want the "failfast" (http://en.wikipedia.org/wiki/Failfast ) system, then you can use the last bit of the monitor or virtual table pointer to store store a boolean that denotes the cleared state of the object. This free space is not available for structs allocated on the heap, dynamic arrays, etc, and then you have to test this bit (in nonrelease mode only?) often, this slows down code a little.
