-// This class implements a file lock that lives on the header of a memory mapped
-// file. This is NOT a thread related lock, it is a lock to detect corruption
-// of the file when the process crashes in the middle of an update.
-// The lock is acquired on the constructor and released on the destructor.
-// The typical use of the class is:
-//    {
-//      BlockFileHeader* header = GetFileHeader();
-//      FileLock lock(header);
-//      header->max_entries = num_entries;
-//      // At this point the destructor is going to release the lock.
-//    }
-// It is important to perform Lock() and Unlock() operations in the right order,
-// because otherwise the desired effect of the "lock" will not be achieved. If
-// the operations are inlined / optimized, the "locked" operations can happen
-// outside the lock.
