So, I added a SynchronizationContext subclass on the main UI thread which does:


public override void Post (SendOrPostCallback d, object state)  
{   
NSRunLoop.Main.BeginInvokeOnMainThread ( () => d
(state) ); 
}   

public override void Send (SendOrPostCallback d, object state)  
{   
NSRunLoop.Main.InvokeOnMainThread ( () => d (state) );  
}   

This fixes the test case.

Ah yeah, it slipped off my radar, sorry. I'll move that to xamarin bugzilla.

Looks like the TaskScheduler is queueing it on the correct
SynchronizationContext, but SynchronizationContext.Post() is just tossing it
into the thread pool willy nilly and letting the thread pool decide what thread
to run it on completely independently.

At this point, I'm in over my head (I was in over my head from the get-go) and
my usefulness in debugging this further and fixing it is basically zilch. We'll
probably need Jeremy Laval to look into fixing this.

Jeremy: *poke*
