hi all,
  How a typical recursive name server handles mutiple queries. i think it 
has forked only once for its task..
  my questions are :
 1) A name server should send a query to some other name server for one of 
the request and wait for some time for its retransmission. Meanwhile if 
some other query times out it has to handle that also..how it diverts it's 
attention..

 2) The above situation becomes more complicated when some of the 
connections are TCP and some are UDP..

may be i am a bit confused.. plz suggest any docs for more info..

thanks in advance
