Daniel Shahaf has suggested also setting
"servers:global:http-bulk-updates=on".

I have a patch that does this, but since turning on bulk updates has
a possible performance penalty, I prefer your approach.

I assume that's because http-bulk-updates defeats caching.  If so,
makes sense.

Please forgive my ignorance: is there a bug filed about ra_serf's
misbehavior here?  Is it eventually going to be fixed and this is
just a workaround, or is the growth in temp file use something we'd
live with permanently?

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?
