commit 9a93dc092c6951cdfa6e05c3885a006e5e56d7d3
Author: Derrell Lipman <derrell at dworkin.(none)>
Date:   Sun May 10 22:58:12 2009 -0400

    Optimize smb_thread_once usage by not calling it if known already called
    
    - The macro SMB_THREAD_ONCE now tests whether the "once" variable is already
      set, and if so avoids calling smb_thread_once().
