Of course it will use them if they're there (if it really needs to, as you pointed out).
but if the OP doesn't want to disable swap, then that doesn't matter. however, the OP does not mention why he wishes not to swap. if it is for security reasons, then encrypting swap is always another layer of protection.
also, as to the original question: I believe there is work going on to patch
the kernel to support the use of user quotas (like disk space usage
) on tmpfs, but it is not a clean solution (yet).
