9//! A shared tokio runtime for running background workers across multiple components.
10//!
11//! This crate provides [`SharedRuntime`], which owns a single tokio runtime and manages
12//! [`PausableWorker`]s on it. Components such as the trace exporter can share one runtime
13//! instead of each creating their own, reducing thread and resource overhead.
14//!
15//! [`SharedRuntime`] also provides fork-safety hooks (`before_fork`, `after_fork_parent`,
16//! `after_fork_child`) that pause and restart workers around `fork()` calls, preventing
17//! deadlocks in child processes.
