New Solaris 7 features

Looks like Sun has been paying attention to the good features of Linux and
implementing them. I guess Sun decided that that game can be played both
directions. :)

The poll(2) improvements should help squid alot.

- Can address 17.5 terabytes of memory, 9TB files
- Arithmetic computations get to use 64-bit registers and operations
- UFS logging (mount -o logging /dev/dsk/c0t0d0s0 /mnt)
- mount "noatime" support
- TCP performance enhancement with SACK, RFC 2018
- New crash dump features
- BIND 8.1.2
- Sendmail 8.9.1b
- improved poll(2) system call (used in many applications)
- increase in number of filedescriptors
- Full Unicode 2.1 support
- Better threading subsystem
- Lots of new CDE apps/improvements
- Netscape 4.05
- directory name lookup cache optimized and now dynamically allocated on
  demand (static before)
- significantly improved paging algorithim, not "on" by default
        add the line: set priority_paging = 1 to /etc/system, and reboot
        - Note, backported to 2.6 kernel patch "-09"
        http://www.sun.com/sun-on-net/performance/priority_paging.html
        IMPORTANT NOTE: Ensure that data files do not have the executable
        bit set. This can fool the VM into thinking that these are really
        executables, and will not engage priority paging on these files.
 - some new commands like
        plimit(1): Set or get resource limits of a process by taking a
        process ID (PID) as an argument (limit and ulimit only work with the
        current process)
        pgrep(1): Find a process by name and print the PID
        pkill(1): Find a process by name and send it a signal specified on
        the command line
        traceroute

Did I mention that "facls" (man setfacl) added with Solaris 2.5.1 are damn
usefull?
