    Hello.

    I have several problems with prefetch. It looks like cayenne-1.1M4 does
    the correct prefetches, but sometimes it has to query for the same
    thing again. The following project illustrate this problem in two
    different ways.

    Take a look at methode doit and doit2 in class PrefetchTrouble.
