+In the alternatepipenullsplit branch, I made what I think is the relevant
+part of LsFiles not use a lazy bytestring, but instead read chunks
+directly to strict bytestrings. It did not change the PINNED amount or reduce
+overall memory use.
+
+So the pinning must be happening somewhere other than where I had assumed
+it was happening.

+The seekHelper version in comment 3 significantly changes the 
+shape of the profile. PINNED is still there, but only a couple mb,
+and it's a constant amount of memory, not an upward slope.
+
+So I think that identifies the main culprit for the mysterious PINNED.
+runSegmentPaths is supposed to stream, but it seems it somehow is hanging
+on to values longer than it should.
+
+Although the max memory use of that version is still around 90 mb
+according to `time`. The profile is flat at 3500 kb.
