+11.6 slow connect to localhost on Windows
+
+ When connecting to "localhost" on Windows, curl will resolve the name for
+ both ipv4 and ipv6 and try to connect to both happy eyeballs-style. Something
+ in there does however make it take 200 millseconds to succeed - which is the
+ HAPPY_EYEBALLS_TIMEOUT define exactly. Lowering that define speeds up the
+ connection, suggesting a problem in the HE handling.
+
+ If we can *know* that we're talking to a local host, we should lower the
+ happy eyeballs delay timeout for IPv6 (related: hardcode the "localhost"
+ addresses, mentioned in TODO). Possibly we should reduce that delay for all.
