Race condition in taps.cljc?

[rob-3]

I have been running the full test suite frequently while developing tests for =, and I nondeterministically get the following error:

FAIL in (tapping) (taps.cljc:27)
expected: (= 104 (clojure.core/deref counter2))
  actual: (not (= 104 106))

I can reliably reproduce this by running:

while true; do
  lein test clojure.core-test.taps || break
done

and letting it run for a minute or two.

I have an M1 Pro and am running on ARM, so if you can't reproduce on x86 this may be why.

I've never used tap> before, but I see a (sleep 50) in the test that I imagine is the root cause.

Great find. I know that @quoll struggled to get those tests working. Sounds like there are still some issues with it.

If you or @quoll are interested in digging into what's going on, let's do that. Otherwise, we can comment out the failing test with a link to this ticket and a brave hero will pick it up at some point.
