So why do all 19 files need to be open if you are processing 1 file at a time?
Do you have simple logic and maybe the Perl experts here can help? ie, present pseudo code of what you want to do, size of files, output desired, intermediate processing needed, platform.

svn::dump::reader
SVN::Dump::Reader(3) User Contributed Perl Documentation SVN::Dump::Reader(3)
NAME
SVN::Dump::Reader - A Subversion dump reader
SYNOPSIS
# !!! You should use SVN::Dump, not SVN::Dump::Reader !!!
use SVN::Dump::Reader;
my $reader = SVN::Dump::Reader( $fh );
my $record = $reader->read_record();
DESCRIPTION
The "SVN::Dump::Reader" class implements a reader object for Subversion dumps.
METHODS
The following methods are available:
new( $fh )
Create a new "SVN::Dump::Reader" attached to the $fh filehandle.
read_record( )
Read and return a new SVN::Dump::Record object from the dump filehandle.
read_header_block( )
Read and return a new SVN::Dump::Headers object from the dump filehandle.
read_property_block( )
Read and return a new SVN::Dump::Property object from the dump filehandle.
read_text_block( )
Read and return a new SVN::Dump::Text object from the dump filehandle.
The "read_..." methods will die horribly if asked to read inconsistent data from a stream.
