Question about collatedSuite()

[Kathey Marsden]

I noticed in CollationTest.collatedSuite()  we run DatabaseMetaDataTest, 
BatchUpdateTest,
GroupByExpressionTest, and UpdateableResultSetTest for each of four 
locales.  I wonder if
that really adds a lot of coverage or if it would be sufficient to run 
them with just one of the
locales.  Thoughts?  It adds a fair amount of time to lang._Suite.
