Sockets are not threadsafe objects, so any API call that uses or
affects them must be done from the same thread. You can move a socket
from one thread to another but you have to do so explicitly, with a
full memory barrier. So you could in theory close sockets from a
different thread but with care to stop using them in the original
thread.
