Subject: The stats now wait until after the client has finished sending all
 its headers before sending the HTTP response back.  This should be more
 standards compliant.

+	* src/reqs.c: Added a new show_stats field in the conn_s structure
+	so that we will process the client's headers properly before
+	trying to send a HTTP response back.
+
 	* src/sock.c (getpeer_string): Removed the hstrerror() call since
 	it's not supported on all machines, and it's not really needed
 	anyway.
