ThreadA into RemoveBlock(), and got info for blockId1
ThreadB into DropFromMemory(), and got info for blockId1
now Thread A, B all want got info.sychronized
B got, and drop block(blockId) from memory, and this block is use memory
only, so it remove from blockinfo. and then release the lock.
then A got, but info is already not in blockinfo.
Did I have miss sth or misunderstand sth? may dropForMemory and removeBlock
can't happen at the same time?
