why linux don't use streams ??

Hi ,
i read about STREAMS and the mechanism it follows to pass on msg
using queue .
I found , it has implimentaions that maintain the connection and
communication efficiently.
But , i came to know that Linux don' t use STREAMS .

Specifically i have seen the TCP/IP stack code implemented in SVR4
arch. based unix os STREAM implementation , and i found it very
intresting.

But Linux uses some other mechanism in implementing TCP/IP stack . IS
there any specific reason to it ?
Is there any drawback exists in STREAMS for which it is not used there
?

See http://www.tux.org/lkml/#s9-9 for an answer
Also, see http://www.gcom.com/linux/lis/ for a STREAMS implementation
for Linux

If you do not understand something, you are doomed to reinvent
it. Poorly.
