The state of .setKeepAlive() is now tracked and code will prevent repeated system calls to setsockopt() when the value has already been set to the desired value for the socket.

There was a problem hiding this comment.
Doesn't this need to include the msec setting as well?

The state of .setKeepAlive() is now tracked and code will prevent repeated
system calls to setsockopt() when the value has already been set to the
desired value for the socket.
make -j4 test(UNIX), orvcbuild test(Windows) passesRationale
The reason for this change is that if keep alive is set for a HTTP Agent, there will
be repeated calls to
net.Socket.setKeepAlive()which in turn will cause many calls tosetsockopt() that are unnecessary since the socket has already been set to
send keep alive packets.
This is much like #31543
