 Tor can to start write to connection just because something wrote to
 conn's outbuf by _connection_write_to_buf_impl(). While connection can be
 blocked on bw still.
 If buckets empty it can't to write anything anyway (need investigation for
 sure).

 Suggested idea to fix, could be looks like:
 {{{
   if (conn->write_event && !conn->write_blocked_on_bw) {
     connection_start_writing(conn);
   }
 }}}

 Kludgy probably. #8111 will fix it generally for 0.2.5 I hopes.
