No, this is not the solution. The OS only can flush out libraries
and other stuff where the use count is zero, but it can't rearrange
memory chunks of a fragmented RAM disk to one big chunk. It simply
cannot *move* memory. - For the special case of the RAM disk, I can
imagine a software that knows all internals of this device and
rearranges that memory, but that doesn't sound trivial.
