Did you try $SIG{__DIE__}?  It's a global setting for that perl
interpreter.  I expect it will catch this.  But it sounds like you
already got what you needed from your 500 intercept.

Sure.  You can just say $XX::Clients::YY::ContentHandler::foo = 1 to
put something in the symbol table.  It doesn't mean the module is

I suggest you set your logging so you can see the exact set of
requests the process received in order (by following the PID), before
having this problem, and then try to recreate it by sending those same
requests with a WWW::Mechanize script.  Maybe that will show you how
your code skipped loading this module.
