Add a simple thread pool with a fixed number of worker threads and a shared work queue. The pool is accessed via ThreadPool::the() which lazily creates a singleton with 4 worker threads. submit() enqueues a work item and signals a condvar. Worker threads loop waiting on the condvar, picking up and executing work items. Worker threads use 8 MiB stacks to match the main thread, since the JS parser can build deep call stacks during off-thread parsing.
