c-ares can be configured to ignore the TRUNCATED flag and just work with
the shortened list of responses it receives over UDP. This patch will
implement that solution in the short-term while we try to solve the
bigger integration issue.
My efforts in the integration area seem to be implying that there may be
a bug in c-ares itself where it's not properly informing the mainloop
when it wants to write, so this may be a very long process.
Self-nack. I've found a real fix that will handle TCP DNS properly. New
patch coming in a new thread.
Delivering value year after year.
