raw_usrreq.c:raw_input() "sockets" variable

[jtc%acorntoolworks.com@localhost (J.T. Conklin)]

Hi,

While reading raw_input(), I noticed it initializes the local variable
"sockets" and increments it each time a process is woken up, but it is
apparently otherwise unused.  I checked TCP/IP Illustrated, and it was
apparently the case back then too.  Is there any reason why this value
is maintained?  Can we expect gcc to optimize it out?  Should it be
removed?
