I think you should use Test::More's "skip" for this, perhaps something
like this:

SKIP: {
   skip "This test is unreliable";

   # explain why
   ok(1.5 < $delay && $delay < 2.5, "-T 2 run around 2 seconds");
}

... or, actually, even better would be to use a TODO block, so that the
test is run and reports its status, but if it happens not to succeed it
will not cause the whole test to fail.  That way you'll accumulate some
evidence that may serve to improve the test in the future until it
works fully:

TODO: {
   local $TODO = "Ths test is unreliable";

   ok(1.5 < $delay && $delay < 2.5, "-T 2 run around 2 seconds");
}
