What about gracefully handle the poison error recovering the old state?
There was a problem hiding this comment.
It can be poisoned if another thread panicked while it has the mutex locked. But this lock is used only 2 times, at startup and at shutdown.
At startup should not be possible to have a poisoned lock, because noone kept the lock before. At shutdown, it can be poisoned only if the startup panicked (precisely, if mem::replace(&mut *tracer_provider, Some(new_provider)) panicked). But in this case shutdown_tracer_provider will not be called.
So, this seems a good case to use expect, like done by opentelemetry::global::set_tracer_provider...

After upgrading this library in our application, we observed the following errors logged after every execution of a scheduled tasks:
This is related to open-telemetry/opentelemetry-rust#1961.
It appears that we should explicitely shutdown the tracer provider, otherwise it doesn't flush all the data when the application terminates. Additionally, the process remains active and the Tokio' runtime complains.
