I'm writting an egui app. And from some point of time my app stop terminating gracefully. And I git few panics instead.

A quick investigation led me to the idea that the order of Drop is not controlled in any way, and thread-local tracing was dropped first, so by the time the tracing method was called with nothing.

panic thread 'main' panicked at 'Thread count overflowed the configured max count. Thread index = 18446744073709551615, max threads = 4096.': /home/sc/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/sharded-slab-0.1.7/src/shard.rs:295   0: ss_common::setup::panic_log::panic_hook

Thanks for the report!

Perhaps just removing the use of tracing in the following two places would suffice?

polling/src/epoll.rs

Line 259 in dd7b207

let span = tracing::trace_span!(

polling/src/kqueue.rs

Line 281 in dd7b207

let span = tracing::trace_span!(

I think it's also reasonable to make tracing optional like done in another smol-rs crate: smol-rs/blocking#60

fix: making invocation of tracing functions from Drop impls optional
c88e22b 
They are now disabled by default and can be enabled using the feature flag
`tracing_in_drop` if necessary.

Closes #231.

Would it be possible to have a proper test for this?
