Or you just fail due to your own miss-management more than just once, and learn that structure is not for the boss but for you, yourself. Happens more often when the style of abstraction is restricted for performance reasons (i.e., no java-like OO and so) and you fall on something like buffer mismatch like I once did (to e fair, it was a bug that repeatably depended on the presence of explicit synchronization calls and there was no documentation about that possibly changing anything).
