Are you sure? I've never proven this to myself, but it has always been my
understanding that with respect the method=POST, the ENV. VAR. CONTENT_LENGTH
would be set to the amount of bytes sent out. THEREFORE, this is why we "read"
that many bytes from STDIN, and only that many. So my point is that
CONTENT_LENGTH
will in one case be a positive number or a -1 -- both atoms. No?

The above of course does not apply to method=GET, because in the latter, all
the data is stuffed in the ENV. VAR. QUERY_STRING. Here we can check to see
if getenv("QUERY_STRING") returns an atom i.e -1, because QUERY_STRING will
either contain a string, or will be undefined.
