On ZFS, it's merely their version of the disk cache, predicatively
reading information it thinks you might need. If an application actively
wants to use that memory, it will release it for use. That seems like
all the more reason to put them all on one logical system, to allow for
more intelligent allocation of memory, and prevent the duplication of
disk cache between the two virtual servers.
