This helps us in several ways: -It allows us to create a single, persistent set of iterators for each contig, finally and definitively eliminating all Shard/FilePointer boundary issues for the new experimental ReadWalker downsampling -We no longer need to track low-level file positions in the sharding system (which was no longer possible anyway given the new experimental downsampling system) -We no longer revisit BAM file chunks that we've visited in the past -- all BAM file access is purely sequential -We no longer need to constantly recreate our full chain of read iterators There are also potential dangers: -We hold more BAM index data in memory at once. Given that we merge and optimize the index data during the merge, and only hold one contig's worth of data at a time, this does not appear to be a major issue. TODO: confirm this! -With a huge number of samples and intervals, the FilePointer merge operation might become expensive. With the latest implementation, this does not appear to be an issue even with a huge number of intervals (for one sample, at least), but if it turns out to be a problem for > 1 sample there are things we can do.
