Hi,

we have some small extensions to the doctesting framework that allow us 
to mark doctests as "#random" so that the result it not checked. Carl 
Witty wrote some code that makes the random number generator in a lot of 
the Sage components behave consistently on all supported platforms.

Yeah, the Sage test suite seems to catch at least one of those in every 
release cycle.

Another thing we just implemented is a "jar of pickles" that lets us 
verify that there is no cross platform issues (32 vs. 64 bits and big 
vs. little endian) as well as no problems with loading pickles from 
previous releases.
