 [kalpesh] I am referring to the variables which are global by their scope,
declared outside
any function body.

  [kalpesh] I meant:
   consider global variable is_main. The interpretation of this variable is
different in
   main process and the rest of the children it forks. I am looking the code
into more
   details for other such type of global vars to achieve the objective of
converting
   processes to threads.
