Are you interested in being a test subject for Uri Guttman's Backwards
module?  <URL:http://www.sysarch.com/perl/Backwards.pm>

The basic design of it reads blocks of a file at a time, starting from
the end (with block boundries that would product efficient disk
access) splits the contents of the block on the newline boundry, pops
off the last one to return to you, and saves the rest for the next
call.

Of course, in you example (tail -1) there is no next call, but used to
create a general tail substitute there might be.
