-------------------------------------
Hi Uwe, I think that even though PriorityQueue doesn't have a size limit, it is
easy to implement a size limit: after an add(), if size() becomes greater than
the bound, you simply poll() to remove the lowest element (this poll() returns
the old object which insertWithOverflow() is to return).
However, I think it's a good idea to compare the performance of Java's
PriorityQueue (used as in the paragraph above) . I'm especially worried about
the slowdown by the fact that adding a small element (below the current heap's
head) in our code just does one comparison and returns, but in the usage I
described above it actually modifies the heap twice (adds the element to the
heap and then removes it).

> PriorityQueue creates an "java.lang.NegativeArraySizeException" when
> initialized with Integer.MAX_VALUE, because Integer overflows. I think this
> could be a general problem with PriorityQueue. The Error occured when I set
> BooleanQuery.MaxClauseCount to Integer.MAX_VALUE and user a FuzzyQuery for
> searching.
