Description
Correct the fork-process example's blanket statement that
BatchSpanProcessoris not fork-safe. The current shared batch processor reinitializes its internal synchronization and worker thread in forked children and clears the inherited queue. The revised text distinguishes that behavior from exporter/transport constraints, keeps the per-worker initialization examples, and links to the signal-specific auto-instrumentation troubleshooting guide.Fixes #4759
