I am. Anyway, this is not the only problem with it.

Please have a look at the code below:

In the CompleteWorker method, "this.async" is assigned to null _after_  this

async.PostOperationCompleted (callback, e);

Therefore, OnRunWorkerCompleted may be (always in my case) executed
_before_, and will see IsBusy as True whereas it should be False.

The test case below prints True on .NET and False on Mono.
Reversing the order of those two statements seems to fix the issue.
