urrlib2 multithreading error

[viscanti at gmail.com]

Hi,

I'm using urllib2 to retrieve some data usign http in a multithreaded
application.
Here's a piece of code:
		req = urllib2.Request(url, txdata, txheaders)
		opener = urllib2.build_opener()
		opener.addheaders = [('User-agent', user_agent)]
		request = opener.open(req)
		data = request.read(1024)

I'm trying to read only the first 1024 bytes to retrieve http headers
(if is html then I will retrieve the entire page).
When I use it on a single thread everything goes ok, when I create
multiple threads the execution halts and the program terminates, just
before the last line (when I execute the request.read(.) ). Obviously I
tried to catch the exception but it doesn't work, the interpreter exits
without any exception or message.
How can I solve this?
