I added a test case for just using read(FILE,1) from a real file, and it's about the same speed as the unpack() on a string (for largish strings).

Of course, this leaves the file open the whole time..but it's wonderfully simple :) I also have a very expensive Netapp filer helping the speed with read-ahead and a huge cache..YMMV.
