Ah, thanks for the context.
It's still not clear to me how we know that ra_serf driving the editor
in a non depth-first manner is the problem here. Has that explanation
been confirmed somehow?
For example, does the workaround mentioned by danielsh work? Does
using ra_neon instead of ra_serf avoid trouble as well? Is there a
simple explanation of why violating the depth-first constraint would
lead to multiple blob (i.e., file, not directory) deltas being opened
in a row without an intervening close?
