/*
  test multi4 Locking&X operation
  This test is designed to show that

  Compared to test_multilock3() (above)
  this test demonstrates that pending read-only/shared
  locks doesn't block shared locks others.

  The outstanding requests build an implicit
  database that's checked before checking
  the already granted locks in the real database.

  For example:

  A blocked read-lock request containing 2 locks
  will be still be blocked, while one region
  is still write-locked. While it doesn't block
  other read-lock requests for the other region. E.g.

/*
  test multi5 Locking&X operation
  This test is designed to show that
  lock precedence on the server is based
  on the order received, not on the ability
  to grant.

  Compared to test_multilock3() (above)
  this test demonstrates that the initial
  lock request that block the following
  exclusive locks can be a shared lock.

  For example:

  All locks except (a) are LOCKING_ANDX_EXCLUSIVE_LOCK (rw).

  (a) lock(ro) 100->109, 120->129 (granted)
  (b) lock 100->109, 120->129 (blocks, timeout=20s)
  (c) lock 100->109           (blocks, timeout=2s)
  (d) lock 110->119           (granted)
  (e) lock 110->119           (blocks, timeout=20s)
  (f) unlock 100->109 (a)
  (g) lock 100->109           (not granted, blocked by (b))
  (h) lock 100->109           (not granted, blocked by itself (b))
  (i) lock (c) will not be granted(conflict, times out)
      as lock (b) will take precedence.
  (j) unlock 110-119 (d)
  (k) lock (e) completes and is not blocked by (a) nor (b)
  (l) lock 100->109           (not granted(conflict), blocked by (b))
  (m) lock 100->109           (not granted(conflict), blocked by itself (b))
  (n) unlock 120-129 (a)
  (o) lock (b) completes
