The invalid argument in subprocess.py is the U in
 self.stdout = os.fdopen(c2pread, 'rU', bufsize)
as I remarked some time ago.

The U means invoke universal newlines, see 
http://www.python.org/dev/peps/pep-0278/.  I thought at first universal 
newlines might not be enabled, but it is, according to the test in the ref 
above.

If I remove the U from the calls to fdopen in lines 549 and 554 then I get:

Traceback (most recent call last):

self.global_options);
 File "c:\program

IOError: (0, 'Error')
Unhandled exception in thread started by
Error in sys.excepthook:

Original exception was:
Lilypond-book returned code 1

If I then comment out the sleep in theading.py, lilypond-book runs to 
completion.  It uses the default values for linewidth, etc, as it can't find 
texi2pdf, of course, just as if I'd bypassed Reinhold's code.
