I'm using the project_reader_t class. But I found the mistake, it was my 
fault, sorry. I forgot that I was passing a list to creator_t.create().
By the way, in create() there's the following 'if' statement right in 
the beginning:

    if not decl_headers:
        self._create_includes()

Could the expression be changed from "not decl_headers" to "decl_headers 
is None"? Because when I pass an empty list to disable the creation of 
include files the expression "not decl_headers" is True and the includes 
get generated anyway.

In my case, it's 20s for parsing the XML file vs 7s for reading the 
cache. So I would prefer the cache. :)
