 Further tests have found something very interesting.
 
 1.  The real issue is - ypserv seems to ALWAYS do dns lookups IF the hosts 
 map is empty.
 Adding one entry (localhost) causes all versions to work as expected 
 (un-patched, new and old).
 
 2.  My previous "FIX" is not a fix, but was accompanied by a change in 
 another input to the problem (the hosts map on the test setup had entries in 
 it - I didn't set-up the test maps).  A back check found that the original 
 version of ypserv on that machine did not do dns lookups.
 
 
 So the workaround is to make sure you have at least one entry in your hosts map.
