apache attempting to re-read POST from STDIN on ErrorDoc redirect

I have the following Apache::Registry script, which posts to itself.  At the
top, I read in the posted values using CGI.  If I receive one of them I die
to demonstrate my little bug.  This causes a SERVER_ERROR to be returned to
apache, which then attempts to perform an internal redirect to a static html
errordoc page.  The problem I am having is that CGI has read the posted
values from STDIN, apache is trying to re-read them on the internal
redirect, which causes it to block.  I have found several solutions to this,
one being to set CONTENT_LENTGTH to 0, or to simply use Apache::Request
instead of CGI.  What I am really interested in is what exactly is
Apache::Request doing to prevent apache from attempting to re-read from
STDIN for post values.

thanks,
