Our first operation is generating sizes for various caller-allocated
buffers. The WithSizes function "suggests" sizes to an anonymous
function that takes a size as an argument and returns a hint how
sucessful the attempt was. If required the same function is called
again with a larger size. Errors and other results of that anonymous
function are "communicated" with variables of the surrounding scope
in wich the function is defined.
