deadlock after updating to tracing-core 0.1.31
Version
I've narrowed the problem down to tracing-core 0.1.31, but here are all the tracing versions in tree after running cargo update, which reproduces the problem.

This is after cargo update.
Platform
x86_64-unknown-linux-gnu in CI and aarch64-unknown-linux-gnu on my computer were both able to reproduce the deadlock, I haven't tried anything else.
Crates
tracing-core
Description
I updated all crates, which included tracing. After updating (which I've narrowed down to just bumping tracing-core from 0.1.30 to 0.1.31), the program (rustc) is stuck in a deadlock when debug logs are enabled. The deadlock happens after quite some logs are already emitted. rustc is single threaded, but all work happens on a second spawned thread, which deadlocks when locking a mutex.

I encountered this in https://github.com/rust-lang/rust/pull/113046
How to reproduce:
- checkout https://github.com/rust-lang/rust
- run
./x setup compiler && x test tests/ui/rustc-rust-log.rs - you can run rustc directly by running
rustup toolchain link stage1 build/host/stage1and thenrustc +stage1
