OK, then we can be sure that the problem (the hang, etc.) is the CGI
environment because Pass 2 (Meta-HTML) and Pass 3 (ePerl) are also
interpreters for the CGI-environment. Ok, then I'll clear any CGI environment
in the WML control frontend for 1.6.1, so WML can be used here, too.  Although
I personally dislike this way of using WML because it is not the way it was
intented to be used for. And it is too slow for this, but ok. Sometimes it can
be useful, yes. At least when someone runs a website authoring environment
with WML as its generation backend.
