should thread_pool be renamed?

[sgerbino]

From the review result:

What's wrong with boost.thread thread_pool was asked somewhere? Well really this type isn't so much a thread pool as an execution context (the base class). I'd suggest renaming to thread_pool_context or threaded_context clears up the confusion here.

Source: Boost review result (conditional acceptance), Boost mailing list, September 2026.

The name is load-bearing: get_system_context() returns thread_pool&, and the type appears throughout the examples and docs. Renaming is a breaking change; options include:

• Rename to thread_pool_context or threaded_context
• Keep thread_pool and add an alias
• Keep the name and document the "execution context that owns worker threads" framing where the confusion arises
