Comment:

 I believe this should be as the definition of `write_blocked_on_bw`
 mentions that it's true iff we are allowed to write.

 {{{
 +  if (conn->write_event && conn->write_blocked_on_bw) {
 }}}

 {{{
   unsigned int write_blocked_on_bw:1; /**< Boolean: should we start
 writing
                              * again once the bandwidth throttler allows
                              * writes? */
 }}}

 `assert_connection_ok()` uses it that way.
