the 'correct' way to do this would be to make the parser part of a thread locals
variable. That way it would be instantiated once by each thread and not by each
It's never been exactly clear why we pay a penalty for importing threading etc
etc, but I assume that's why we never created these variables that way.

I suspect that all the other threading issues will now surface eg all the module
level stuff in pdfbase/pdfmetrics.py.
In addition none of our accelerators has any real notion of multi-threaded
politeness. Hopefully that's enforced by python itself.
