To be honest, I don't really know the details, but it seems to work fine. A
quick look at ipython:

planck[IPython]> svn update
At revision 661.

planck[IPython]> svn diff -r 10 genutils.py | tail
-
-    Deprecated: this function has been superceded by timing() which has better
-    fucntionality."""
-
-    rng = range(reps)
-    start = time.clock()
-    for dummy in rng: func(*args,**kw)
-    return time.clock()-start
-
-#*************************** end of file <genutils.py> **********************

Revision 10 was most certainly back in the early CVS days, and the wholesale
renaming happened when I started using svn, which was around revision 600 or
so.  There may be other subtleties I'm missing, but so far I haven't
experienced any problems.
