What does your intuition tell you this code does?

d=>sub{
    $wait = 0 unless abs($wait);
    $wait = -34;
},

In particular, abs returns the absolute value. The absolute value of -34 is 34, which is "true". Since your condition is never false, you never fall through to the action of the "unless" clause.
