cgi "print statement" in multithreaded enviroment?

[vegetax]

How can i use cgi'like print statement in a multitreaded web framework?
each thread has its own Servlet instance with request/response objects,
sys.stdout = self.response(which is a file like object) wont work because
all threads will set the same file object and it will be a concurrence
mess.

I am out of ideas here,so any hacks welcome =)
