Should also be @volatile due to assignment on line 466 below.

Would it simplify finding bugs if this method would throw an exception (e.g., IllegalStateException) in case it is attempted to resume a non-interrupted pool?

In the PropertyStore the interrupt is implemented as @volatile var isInterrupted: () ⇒ Boolean. Therefore I call resume every time the client waits for quiescense, which should resume the store if it was interrupted.

I think it would be good to add a test case where more than one task is interrupted. Also, there should be a test case, where only one of two tasks is interrupted, because the interrupt is too late for the first task.

"interrupt" -> "suspend". The pair suspend/resume is much more common. Moreover, interrupt already has a different meaning for threads on the JVM (including InterruptedException etc.), so it is actually quite confusing to call this method interrupt!

Changed to suspend.
