ExceptionContainer	AsSyncTask (void(DerivedInstrT::*TaskFunc)(TaskFuncArgTs...) const, ArgTs &&...Args) const
	Calls a (derived) instrument's function which inserts a task into the instrument's task queue synchronously. This means that `AsSyncTask()` blocks until the task has been executed or aborted.

If this happens (e.g. in a module thread), the instrument data's mutex is locked recursively. In principle, this does no harm since Util::ISynchronizedPointerLockable supports that.

template<typename TaskT , typename... ArgTs>
void	MakeAndEnqueueTask (ArgTs &&...Args) const
	Calls `MakeTask()` to construct a new task and subsequently enqueues the task into the instrument's task queue. Logical const-ness: this is a const member function to allow pointers to `const` `InstrumentBase` inserting tasks into the instrument's task queue. These kind of pointers are e.g. returned by RunnableInstance::GetOwner() which can be called by tasks' TaskBase::RunChild() functions. For `const` `InstrumentBase*`, it is possible to insert tasks into the task queue, but not to change the `InstrumentBase` object itself (e.g. calling Object::Reset()). More...
