-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 milliseconds 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 are 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.

 11.7 signal-based resolver timeouts
 
  libcurl built without an asynchronous resolver library uses alarm() to time
