Description of problem:

  Generating, or regenerating, metadata for an object (not a container or
  account) involves multiple stat system calls when one will suffice.

Version-Release number of selected component (if applicable):

  RHS 2.0

How reproducible:

  Every time.

Steps to Reproduce:
1. strace object-server process
2. PUT a new object
3. GET that object
4. Observe stat system calls made in strace output

Actual results:

  Multiple stat system calls made.

Expected results:

  One system call made on behalf of the GET operation.

Additional info:

  See http://pastebin.test.redhat.com/110818 from lines 226 through 243,
  you'll notice the following stat() and fstat() calls made to the file
  being fetched ("testfile.txt"):
    * Line 226, stat()
    * Line 235, stat()
    * Line 237, fstat() of same file open'd on fd 15
    * Line 238, stat()
    * Line 243, fstat() of same file open'd on fd 15

  These 5 calls can most likely be reduced to at most one.
