Subject: RE: File change notification?

Dale, Nobu,

Thanks for the tips on direct calls to Win32. That's the way 
I'm going to go. I think UNIX variants don't support file change
notification so I don't feel bad about going directly to bad old
Windows.

For now I'm happy with blocking everything in the Windows Kernel.
If need be I can always spin off a separate Ruby process.

For future refinement I have one follow-on question: can I build
an extension DLL that creates it's own NT thread which would block
on the change notification handle? Can the NT thread signal a
blocked Ruby thread waiting on a mutex? I suppose the answers must
be 'yes' but I'm not sure if I'm overlooking something.

Thanks,
Andrew
