So let me be ( I hope) much more clear: Below my publisher handler:

import mod_python.apache
page = """<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html><head><title>Test page</title></head>
<body> Test </body> </html>"""

def req_write(req):
	req.status = mod_python.apache.OK
	req.content_type = "text/html; charset=utf-8"
	req.send_http_header()
	req.write(page)
	open("/tmp/marker","w") # Test if we have exceptions 
		#before returning from handler

def req_return(req):
	req.status = mod_python.apache.OK
	req.content_type = "text/html; charset=utf-8"
	req.send_http_header()
	return page

http://abbon.ant.vpn/test.py/req_return - returns what expected
while 
http://abbon.ant.vpn/test.py/req_write returns more some additional data 
(reaching marker):

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html><head><title>Test page</title></head>

As far I understand publisher both results should be the same ...
Perhaps my mod_python /apache are broken ?
