[Pdx-pm] Big tied arrays

I've got a tied array class that can grow to a very large size (using  
multiple files) mostly written.  Am I reinventing the wheel?  I  
haven't tracked anything like it down on CPAN so far.  In a nutshell,  
the scheme uses index files which store lookup data (filenum, offset,  
length) against the data files, allowing storage of arbitrary  
content.  Deletions don't disappear from the data files unless you  
optimize the whole thing.

The DB_RECNO option from DB_File uses a single-byte record separator,  
so that's out.  Anything else?
