> The parser is currently a real memory burner. I fed it a 4MB CSV file and ran
> the TPTP profiler. As you can see the parser creates around 100MB of garbage
> whereas it could (in really optimized) use around 4MBs. Such figures are not
> acceptable within a server environment. Please attach insights and patches to
> this issue report.
