That could work, but there are a few potential issues.  'tail' does slightly
different stuff on different platforms.  Maybe you're on Windows and it
isn't available.  Maybe it mangles your output (I know that some coreutils
tools try to be encoding-aware, I don't know if 'tail' is one).  Maybe you
want to get blocks of bytes off the end rather than lines, etc.  Then you
also need to worry about housekeeping for a subprocess, which always turns
out to be a little trickier than you first expect.
