Good point.  When select() returns an error, we ought not to write.  So, my
code could be put right after check_timeout().  The bug is caused by the fact
that select() doesn't return an error.  It keeps returning 0.  In a perfect
world, select() would detect that the socket is in an error state, but it
doesn't.  It sees a full transmit buffer and says that the socket is not ready.

How about this:

if (count == 0) {
  check_timeout();
  --- my patch ---
}

if (count <= 0) {
   --- leave this as is ---
}
