This intentionally borrows from `RefCell`s before conditional code to try to prevent regressions like rust-lang#13646 without exhaustively covering every case that could hit these `BorrowMutError`s with complicated tests. I tested this by ensuring the registry code path panicked before rebasing on top of rust-lang#13647. Once I rebased, the panic went away. Co-authored-by: Ed Page <eopage@gmail.com>

This intentionally borrows from
RefCells before conditional code to try to prevent regressions like #13646 without exhaustively covering every case that could hit theseBorrowMutErrors with complicated tests.How should we test and review this PR?
I tested this by ensuring the registry code path panicked before rebasing on top of #13647.
Once I rebased, the panic went away.
