Subject: r3886: Trying to understand delayed file write update times. Added
 another test that uses 2 connections and queries the time via pathinfo, not
 fileinfo. MSDN states : "When writing to a file, the last write time is not
 fully updated until all handles used for writing have been closed." - but
 this is obviously untrue. W2K3 seems to use a 2 second granularity for this.
 Next I'll try using SetFileTime equivalent to see if this takes the same time
 to take effect. Jeremy. (This used to be commit
