Well *ideally* you shouldn't be getting any test failures :-).  But I 
could imagine than running Solaris within a VM might cause some 
problems.  Which tests are failing?

Tests I'd be worried about for the float repr change include: 
test_float, test_complex, test_math, test_cmath, test_ast, test_format, 
test_marshal, test_pickle, test_json, test_builtin, test_capi.
