Hold on here for just a sec...
It is quite possible to do memory management aimed at one container while that container's memory still participates in the main VM.
There is overhead here, as the LRU scanning mechanisms get less efficient, but I'd rather pay a penalty at LRU scanning time than divide up the VM, or coarsely start failing allocations.
