Breaks DCE with zephyr

[i-am-the-slime]

In some FFI there's references to exports.useMemo_ in other exports.something functions. This confuses the aggressive FFI employed by zephyr. I'd like to rewrite the FFI in such a way that this doesn't happen.

Looks like I was lying. I'm completely confused now.

Edit: Okay it's useEqCache_ now, I think.
