-** Windows file locking notes:  [similar issues apply to MacOS]
-**
-** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
-** those functions are not available.  So we use only LockFile() and
-** UnlockFile().
-**
-** LockFile() prevents not just writing but also reading by other processes.
-** (This is a design error on the part of Windows, but there is nothing
-** we can do about that.)  So the region used for locking is at the
-** end of the file where it is unlikely to ever interfere with an
-** actual read attempt.
-**
-** A database read lock is obtained by locking a single randomly-chosen 
-** byte out of a specific range of bytes. The lock byte is obtained at 
-** random so two separate readers can probably access the file at the 
-** same time, unless they are unlucky and choose the same lock byte.
-** A database write lock is obtained by locking all bytes in the range.
-** There can only be one writer.
-**
-** A lock is obtained on the first byte of the lock range before acquiring
-** either a read lock or a write lock.  This prevents two processes from
-** attempting to get a lock at a same time.  The semantics of 
-** sqlite3OsReadLock() require that if there is already a write lock, that
-** lock is converted into a read lock atomically.  The lock on the first
-** byte allows us to drop the old write lock and get the read lock without
-** another process jumping into the middle and messing us up.  The same
-** argument applies to sqlite3OsWriteLock().
-**
-** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
-** which means we can use reader/writer locks.  When reader writer locks
-** are used, the lock is placed on the same range of bytes that is used
-** for probabilistic locking in Win95/98/ME.  Hence, the locking scheme
-** will support two or more Win95 readers or two or more WinNT readers.
-** But a single Win95 reader will lock out all WinNT readers and a single
-** WinNT reader will lock out all other Win95 readers.
-**
-** Note: On MacOS we use the resource fork for locking.
-**
-** The following #defines specify the range of bytes used for locking.
-** N_LOCKBYTE is the number of bytes available for doing the locking.
-** The first byte used to hold the lock while the lock is changing does
-** not count toward this number.  FIRST_LOCKBYTE is the address of
-** the first byte in the range of bytes used for locking.
