// TODO: We should use async await (once we get 4.5) or normal Task Continuations on Command processing to prevent blocking the TaskScheduler.
// For now we use TaskCreationOptions 0x10, which is actually .net 4.5 HideScheduler.
// This will detach the scheduler from the thread, causing new Task creating in the command to be executed on the ThreadPool, avoiding a deadlock.
// Please note that the issue only shows itself on mono because since Microsoft .net implementation supports Task inlining on WaitAll.
