But this will only work, if you run everything in a single thread, since 
reportlab uses module-global variables, unless you use thread-local variables 
fr this, which I think you don't. The safest way is always to create a 
separate sub-process for PDF rendering. You may want to check out z3c.rml, 
which Roger Ineichen did just that.
