On Linux, if you're using tmpfs as the cache, what's the difference

Does memcache swap out? I was convinced it did not.
I don't believe that it does, but I was asking about the hypothetical
case in which it would allow swapping.
It used to be said (back when warlord was maintaining linux-afs and
Transarc 3.4a was the main release) that the memcache was much less
efficient than the disk cache and that it was better to use disk cache
in a ramdisk. Both have been pretty thoroughly overhauled since then,
though.
