It is my understanding that if memory is requested and written to (maybe during your file reads) the guess will use the host memory and not give it back. The give back will happen when something else needs the memory (but ONLY if you have current VMware guest installed). You stated the app increases private mem usage - if the app still has allocation of the mem, the OS is likely not going to give it back when VMware asks as the OS will think the VM is still using the memory actively.
