The number of retries and the timeouts are all handled by libc, I
believe.  In any sane system, calling getaddrinfo() twice should not
make any difference (except e.g. cases where the DNS server is
temporarily unreachable, of course).  So I don't think that is a good
solution (it would only mean we take a lot more time before failing, but
we'll almost always fail anyway).

In the good news department, we believe we have found the problem with
name lookups when the network changes.  It seems glibc does not notice
changes to the DNS server addresses automatically.  But it seems it does
provide a function that can force it to reload the configuration.  There
is currently some discussion on how we can use it without breaking
anything.
