In that case, I believe you are seeing a bug in
FOP that causes it to generate extra blank pages.
When I process my book which has several part
elements with the XEP FO processor and double.sided=0,
each Part always starts on the next available page, even
if it is even.

You might peek inside your FO file to see if the
fo:page-sequence for each part has this attribute:

initial-page-number="auto-odd"

It shouldn't.  If it does, then something is going wrong with 
handling the double.sided parameter.  If you don't
have that attribute, then the FO processor should not
be jumping to an odd numbered page.
