Re: os.pipe() error in lilypond-book

[Trevor Daniels]

Hi Ralph

I'm still trying to track this down.  It looks like it
might be a Windows-specific problem as I can't reproduce
it on ubuntu.  It might even be specific to my computer,
so I'll continue investigating on my own for a bit
longer.  I'm limiting myself to 30 mins or so a day, so
it might take a while ...
