As somebody who has worked in Sun's Solaris engineering department for
several years I can assure that a considerable number of bugs where
fixed in the Solaris 10 development sources (long before its release)
and the fixes were backported to Solaris 9 and 8 (or even further)
afterwards.

A lot of these program ...
1.) ... don't use getaddrinfo() at all but older functions like
    gethostbyname().
2.) ... don't perform many DNS queries.
3.) ... create child process to deal with incoming connections. And when
    the child process terminates all the leaked memory is freed.
