Hmmm... you already found that Meta-HTML is the bad guy here, so I've poked
around its sources and found that under a CGI environment it tries to
automatically import this. Actually the CONTENT_LENGTH variable is inspected.
Because you say that your CGI-script received some stuff and then wants to
process it via WML, I'm right when I'm assume that your CGI script is invoked
via POST method?
If yes, then the error is clear. As a workaround you had to remove or clear
the CONTENT_LENGTH environment variable before running WML to avoid a
re-import if it in Meta-HTML. Just add ``CONTENT_LENGTH='' in front of the WML
call. When it then never hangs I can clear these variables in WML 1.6.1 per
