urllib leaves connections/sockets waiting. BIG problem!!!

[binaryj]

hi i am using urllib2 to do some automated web thing.
basically i hit on sites and check the price what they are offering
for their product and then decide if i want to lower or increase my
pricing.so in short i have to hit hundreds of sites!!!!!

for the problem:
=============
i run 20 threads all do the same stuff. (hit and run :) )
after around 10-15 hits(per thread) hits the thread does nothing. it
freezes. slowely but STEADILY all the threads end up with the same
fate :(

i did some netstat and found out that the connecton(sockets) the
program had opened are waiting the CLOSE_WAIT state !!

netstat -t
tcp        1      0 192.168.1.2:4882        host-blabla:www
CLOSE_WAIT
tcp        1      0 192.168.1.2:4884        host-blabla:www
CLOSE_WAIT
tcp        1      0 192.168.1.2:4375        host-blabla:www
CLOSE_WAIT


OUTPUT OF PROGRAM:
THREAD: #Thread-2 getting price from webi-d  7511975 DONE !!!
