I'm wondering if constrainting TValue to INumberBase<TValue> would work

Race condition with Interlocked.Exchange
I'm thinking this might do the trick 
ObjectWrapper? value;
lock (this.stateLock)
{
    value = Interlocked.Exchange(ref this.currentValue, null);
    this.ClearCriticalState();
}
ObjectWrapper? value;
lock (this.stateLock)
{
    value = Interlocked.Exchange(ref this.currentValue, null);
    this.ClearCriticalState();
}

I guess InvokeAsync updated the value after the first ExecuteCore, and then that cleared the value. But because InvokeAsync was called during the first ExecuteCore, the critical state got set so ExecuteCore was called again

Looks like InvokeAsync was called in the same 10~ microsecond window as ExecuteCore

Which is why I introduced the critical continue state, which tells the task to keep running since InvokeAsync was invoked very closely around ExecuteCore

InvokeAsync could get called just before or just after ExecuteCore is invoked, and even just before and just after it completes

It's why I added the lock so that I could at least get a slice of time to sync everything
