Fiber.interrupt not interrupting FiberAsync.run

[cgordon]

As the title suggests, calling Fiber.interrupt on a Fiber that is parked in a call to FiberServerSocketChannel.accept does not cause an InterruptedIOException to be thrown, as I would expect from reading the code. I have traced the problem into FiberAsync.run, but am not fluent enough in the semantics of park/unpark to get further. Here is a simple main method that reproduces the problem:

Here is the output of the flight recorder for a run of that method:

Here is the gradle.build file I used:
