This is really weird.

select npoints(the_geom), npoints(Simplify(the_geom, .1))
from province

results to:

1:	25290,		39
2:	23978,		43
3:	25999,		22046
4:	4996,		19
5:	24679,		31
6:	50819,		43120
7:	31899,		71
8:	63292,		45
9:	84990,		70460
10:	12878,		15
11:	1047,		8

The data is lat/long wgs84, what could cause rows 3,6 and 9 not to 
simplify as much as the others?
