I thought CD burners, the new ones, have enough buffer to survive o/s and app underflow. I guess it depends on how long a track is, or whether the firmware.CD hardware/medaia allows it to see where it left off and turn on writing right there.
The mmap()/munmap() is neat, though, as it allows a 32 bit program to use unlimited RAM. Things mapped stay in memory even if unmapped and are available to a new map, so you can swap super-pages of a huge set of files in your limited address space. Of course, mmap64() allows you to leave it all mapped, at the cost of fatter code. Some sort of client-server arrangement allows tight 32 bit clients to access all that data on a tight 64 bit data server.
