Summary: As discussed in our internal group, we don't get much use of seek compaction at the moment, while it's making code more complicated and slower in some cases. This diff removes seek compaction and (hopefully) all code that was introduced to support seek compaction. There is one test case that relied on didIO information. I'll try to find another way to implement it.
