  A few years ago the developers, "in their infinite wisdom", decided to
enable the ipv6 USE flag by default.  I found out "the hard way", when
internet-enabled apps like Firefox sat there, spinning their wheels for
a minute, before timing out the IPV6 lookup and falling back to IPV4.
Since then, I have always done a --pretend update run and check the
output, before doing the real update.  And I've switched to beginning my
USE variable with "-*".

  There is the option of setting USE="-ipv6" the more timid users.  I
don't understand the point of defaulting to IPV6.  The vast majority of
Gentoo users probably still run IPV4-only.
