Scott,

Thanks for this.  It looks like I can't use it right now though.  I think
that the CGI is completing, but the Apache process is locking up.  My
reasoning is that I don't see any of the CGI processes, but I do get
errors in the Apache error log:

[Fri Dec 05 10:03:22 2003] [warn] child process 4239 still did not exit,
sending a SIGTERM

when I restart Apache.  Also, I did get the CGI running off of the command
line, as Mike suggested, and it runs just fine.  Has anybody else seen
this in Apache 2.x?  Thanks.
