In the context of this thread my answer was wrong - I thought tmpfs allocates from kmem for bulk storage, like one mode of mdmfs does. In this light, it shouldn't compete with zfs nearly as much as I assumed. On the bright side, and a bit offtopic, amd64 will get the ability to allocate a lot more of memory for kmem soon, so people having problems with zfs will be relieved.
