Speaking both as a member of the group that designed the new I/O
facilties for JDK 1.4, and as a potential user of an NIO-friendly
lexer/parser generator, I'd like to emphatically support Xuâns

If it does get taken up, please feel free to pester me for advice on
how best to exploit the new APIs.

Cheers,
