Different situation. It is not in-page embedded Perl and is not
really subject to Safe checking in the same way -- it is pre-compiled
and not interpreted.

There are a number of reasons for this restriction -- trust me that
I have spent many hours on these issues and have done the best I
could with it. 

Of course if someone *really* wants to get into the guts of this and try
to improve it, they can go right ahead. I would ask that they don't ask
me any questions about it, though, until they have put at least 10% of
the weeks of time I have spent on getting IC embedded Perl to the point
that it is at. 8-)
