[svn-r8392] Purpose:
Bug fix.

Description:
The data verification code didn't work.  Also numerous minor bugs.

Solution:
Re-wrote data write and verification code.  In particular, I
modified the verification code so it actually verifies data.

In the future, this test should be modified so it exercises
object deletes and chunk I/O.

Platforms tested:
