I timed them with the following code and it occurred to me here's a possibly
good case where aspect-oriented programming would be nice.  Anyway, the
results first:

	<function endsWith at 0x100f94d0> : 0.36 seconds.
	<function sliceIt at 0x100f9510> : 0.07 seconds.

The test:

    #! /usr/bin/env python

    import time

    def getString(n):
        s = "s" * n
        s = s + '\n'
        return s

    def endsWith(s):
        s.endswith('\n')

    def sliceIt(s):
        s[-1:] == '\n'

    def timeIt(func):
        n = 100000000
        s = getString(n)
        timeIn = time.time()
        func(s)
        timeOut = time.time()
        print "%s : %1.2f seconds." % (func, (timeOut - timeIn))

    timeIt(endsWith)
    timeIt(sliceIt)
