+ test multi3 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_multilock2() (above)
+ this test demonstrates that completely
+ unrelated ranges work independently.
+
+ For example:
+
+ A blocked lock request containing 2 locks
+ will be satified before a subsequent blocked
+ lock request over one of the same regions,
+ even if that region is then unlocked. But
+ a lock of a different region goes through. E.g.
+
+ All locks are LOCKING_ANDX_EXCLUSIVE_LOCK (rw).
+
+ (a) lock 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
