Thank you for the report! Unfortunately I could not reproduce the bug,
but I agree that mgs_transport_write not setting errno might be an
issue. Could you check if the attached patch fixes the problem?

If this does not help, would you be able to provide me with a minimal
configuration that can reproduce the problem (e.g. Apache conf, CGI
script for the slow proxy backend, shell script to send requests)? Just
the information which client you are using might be helpful as well
because your report looks like a bug that might be exposed by specific
client behavior at end of connection.
