I consecutively allocate 3 chunks of 10-50Kb each. In order to be able to resize them when need arises, I use handles. When I later resize one of them, thinking for small devices with little heap, should I unlock the other adjacent chunks to give more freedom to the OS in this operation? If so, can I only unlock the chunks allocated after the one that is to be resized?
For chunks that large, if you are in a position to do so, then I would say yes, unlock all three. It couldn't hurt, and can only do good.
Unlocking the the lower block would help if the heap needs to be compacted. If you don't unlock it, you may fragment the heap in such a way that you can't resize the middle block.
