Comment:

 This was the change that perf.h.o reported:
 {{{
 nofib/time/cryptarithm1         0.401   + 4.99% 0.421   seconds
 }}}

 Since cryptarithm1's runtime is currently under 0.4 seconds again on
 perf.h.o, I think it's safe to close this ticket, and call it an anomaly.

 {{{
 nofib/time/cryptarithm1         0.397   =       0.397   seconds
 }}}
