Answer 1

You can utilize some kind of shared name resource that allows threads that spawn to register a name (perhaps a map of thread id to name). Your logging system can then place a call into a method that gets the name via the thread ID in a thread-safe manner.

When the thread dies, have it remove it's name from the mapping to avoid leaking memory.

This method should allow all threads to be named, not just main.
