Why? Lynx, for instance, uses gethostbyname and kin for asynchronous
operation, too. It just starts an extra thread to run them.

In Cygwin you have the minires resolver lib, which allows you to call
the resolver functions as if on a POSIX system. As for the gethostbyname
function, you can create asynchronous requests by calling the functions
in a thread.
