 I tried making a borg repo with 100 archives of a 1000 object git-annex
 repo. The length of each item was 142 bytes, so all the items should
-need about 15 mb of memory. git-annex sync used half a gigabyte of memory.
-So that's a test case for this bug.
+need about 15 mb of memory. git-annex sync used more than 2 gb
+of memory. So that's a test case for this bug.
+
+Looks like around 500 mb is used listing the repo contents, and
+then after all the borg list is complete, it uses much more memory
+building the git tree.
+
+I was not including building the git tree in my estimates. I see
+that Annex.Import uses recordTree, which does have to buffer the whole
+tree in memory, but this seems much more memory than that.
