[mod_python] Large req.writes prevent header from being outputted?

Mike - 

I'm not able to reproduce this. I just tried something similar with an 8Mb
file, and I get all the headers and data correctly.

Anyone else seeing this behaviour?

Could the problem be something with your client? I used wget -S to test my
results.
