+By default, glibc performs IPv4 and IPv6 lookups in parallel since 
+version 2.9 (though many distribution packages of glibc are known 
+to disable that behavior in this version). Some appliance DNS servers 
+cannot handle these queries properly and make the requests time out. 
+This option disables the behavior and makes glibc perform the IPv6 
+and IPv4 requests sequentially (at the cost of some slowdown of the 
+resolving process).
