Comment(by jdemeyer):

 It seems that testing this module can give enormously different timings
 depending on the machine.  Any clue why?

 On `sage.math.washington.edu`:

 {{{
 $ ./sage -t "devel/sage/sage/sandpiles/sandpile.py"
 [...]
 Total time for all tests: 23.7 seconds
 }}}

 But on my laptop (Gentoo Linux, Intel Core 2 Duo, gcc 4.4.3):
 {{{
 $ ./sage -t "devel/sage/sage/sandpiles/sandpile.py"
 sage -t  "devel/sage/sage/sandpiles/sandpile.py"
 *** *** Error: TIMED OUT! PROCESS KILLED! *** ***
 }}}
 (i.e. it takes more than 360 seconds)
