Multiple approachs:
1) uv_set_threadpool_size(int) can be called just once (per loop?).
2) Keep state:
- int uv__num_threads_in_use: number of active thread being used.
- int uv__threadpool_size: max number of threads (seteable, and at some
point can be least than uv__num_threads_in_use).
- When calling uv_queue_work(), just add a new thread if
uv__threadpool_size > uv__num_threads_in_use. Otherwise enqueue it.
- When a work ends check if (uv__threadpool_size < uv__num_threads_in_use).
If so kill/delete the thread associated to that work.
Does it make sense?
