I hit the send key too quickly -- my bad!

What I was going to say is:

CONTENT_LENGTH will either be empty or contain the number of chars/bytes
sent. So 
if atom(tmp) then

checks to see if getenv() returned a number, right? If true, we have that
many chars/bytes. If 0 CONTENT_LENGTH was empty.

Do I need another cup of coffee? or something? It seems that the logic
is backwards. TIA...  (now hit the send button, duke)
