> * If you open a few connections, and one of them breaks (for example, 
>   due to a network error), another connections can be locked for time, which is 
>   equal to network timeout of the broken connection. This happens due to 
>   working with sockets in blocking mode and due to using one Selector for all 
>   connections. 
> * All connections could become locked forever due to races between 
>   Driver and Selector objects. Driver object removes itself from the Selector 
>   non-atomically and a situation when Driver is alredy closed, but the Selector 
>   refers to it could happen. In this case select() call in the Selector raise 
>   an exeption due to self._transport.fileno() call on Driver where 
>   self._transport is None. The selector doesn't handle errors on select(), so 
>   the selector's thread will be stopped due to unhandled Exception. 
> * There is no checks on EINTR error on os.* calls.
