 win_iocp_socket_service use select_reactor with OwnThread=true for
 performing connect operations. While finish connect op, handler copy-
 constructed on the stack (reactor_op_queue::do_complete/do_destroy), but
 constructor invoked from another thread (internal thread of
 select_reactor). That means, that if our handler have specific copy-
 constructor (for example, we use intrusive_ptr for holding this in bind_t)
 we need to synchronize it with main thread (or use interlocked functions).
