Suppose a collection has occurred. Then there are big gaps where memory has been reclaimed, between blocks that are still in use. If there is no copying collector, how does the gc avoid fragmentation? I see that each page of memory is released as it is found to contain no objects still in use. Is that the only mechanism used to control fragmentation? Bill.
