Just to make sure I'm understanding correctly, the reason this does not need a try_borrow_mut anymore is because there's no possibility of a recursive lock, right? I believe the try_borrow was added in e2fd2df FWIW.

Right yeah the scope of the borrow should always be one line of code which doesn't execute other arbitrary lines of code (e.g. an arbitrary Write implementation). As a result we should be guaranteed that it always succeeds.

@bors: r=Mark-Simulacrum I agree! This is all probably great reasons why |

@bors r- Looks like some tests are passing now and are expected to fail?

…Mark-Simulacrum std: Don't abort process when printing panics in tests This commit fixes an issue when using `set_print` and friends, notably used by libtest, to avoid aborting the process if printing panics. This previously panicked due to borrowing a mutable `RefCell` twice, and this is worked around by borrowing these cells for less time, instead taking out and removing contents temporarily. Closes rust-lang#69558
