There are more calls to gethostbyname() after the get_myname () call. 
load_interfaces() is doing gethostbyname() for every single value of the
"interfaces" parameter of smb.conf. If interfaces doesn't contain an
ip_address/netmask pair load_interfaces() tries to resolve the value
via gethostbyname() :(
