Did you read my example with the soundcomponent? If it tries to allocate a
too large soundbuffer, an OutOfMemoryException will occur. But why should
the rest of my application care about that? Since the request to allocate
the large soundbuffer failed, we have still enough memory. We have no
background music playing but we are far far away from trouble.

You may be wrong,

And if Iam wrong then the App crashes when there is really a problem which
affects vital parts of my app, but in most cases this is not the case.
