unsigned long it better for the size arguments
...
The new syscalls should use unsigned long not size_t. The parameters
are not a direct measure of memory size.

Cache network interface information
...
Whenever getaddrinfo needed network interface information it used the
netlink interface to read the information every single time. The
problem is that this information can change at any time.
The patch implements monitoring of the network interfaces through
nscd. If no change is detected the previously read information can
be reused (which is the norm). This timestamp information is also
made available to other processes using the shared memory segment
between nscd and those processes.
