The sorter was dropping on the floor the returned Status of the PrepareRead() calls. PrepareRead() tries to Pin() blocks. In some queries with large sorts, those Pin() calls could fail with OOM, but because the sorter was ignoring the returned Status it would happily put the unpinned block in the vector of blocks and eventually seg fault, because the buffer_desc_ of that block was NULL. This patch fixes this problem and adds a test that eventually we may want to move to the exhaustive build because it takes quite some time. It also changes the comments of the sorter class to the doxygen style.
