Heck I don't know...  Any work you guys do should be applicable to
Xastir-2 or Xastir-TNG or whatever we're going to call it, so it
won't be wasted effort.  My opinion is just one out of several
developers...  Don't give it too much weight.

My comment earlier that the forking was done in order to provide a
timeout should DNS not respond was meant to trigger some thought as
to whether that method made sense for what you guys were doing.
Don't keep the fork if you can come up with another general-purpose
method to provide a timeout capability.  We use that method in other
places too.
