> A terminated pthread should be joined or detached so that its associated
> resources are released.
> 
> The "ice-reset-<vf_id>" threads are used to service some reset task in the
> background, but they are never joined by the thread that created them.
> The easiest solution is to detach new threads.
> 
> The Windows EAL did not provide a pthread_detach wrapper but there is no
> resource to release for Windows threads, so add an empty wrapper.
