Description
Current behavior is that new threads spawned from the main thread will not record anything.
Detect when a thread starts and begin recording then. Take care not to overwhelm the filesystem with thousands of AppMaps in the case where there’s a large thread pool processing lots of messages per thread.

Research direction
No files, tests, or entry points are named. Start by tracing how recording begins for the main thread and where new thread creation can be observed; then determine how to record spawned threads without producing excessive AppMaps for large thread pools. Done means spawned threads record as intended while filesystem output remains bounded.
