Hi, thanks for diagnosing this and producing a patch!  I ended up
turning the condition around, so that all three stanzas still test
"!nowait"; which seems a bit easier to follow.

TBH I'm quite troubled by the fact that this test only failed once on
each animal; they all had a lot of successful runs after that.  I wonder
if this is because coverage is insufficient, or is it just bad luck.

I also wonder if this bug is what caused the random failures in the test
case I tried to add.  I should look at that some more now ...
