Well, in the case of my_eye[] and half_eye[], it seems to me that they
are not always recomputed. In do_owl_defend() we have :

  /* First see whether we might already be alife. */
  if (escape < MAX_ESCAPE) {
    if (owl_estimate_life(owl, ...

which makes me wonder how accurate are owl_eyespace() constraints once
the escape variable has reached MAX_ESCAPE...

Or am I missing something again ?
