+ test multi4 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 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.
+
+ (a) lock(rw) 100->109, 120->129 (granted)
+ (b) lock(ro) 100->109, 120->129 (blocks, timeout=20s)
+ (c) lock(ro) 100->109 (blocks, timeout=MAX)
+ (d) lock(rw) 110->119 (granted)
+ (e) lock(rw) 110->119 (blocks, timeout=20s)
+ (f) unlock 100->109 (a)
+ (g) lock(ro) (c) completes and is not blocked by (a) nor (b)
+ (h) lock(rw) 100->109 (not granted, blocked by (c))
+ (i) lock(rw) 100->109 (pid (b)) (not granted(conflict), blocked by (c))
+ (j) unlock 110-119
+ (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 (pid (b)) (not granted(conflict), blocked by itself (b))
+ (n) unlock 120-129 (a)
+ (o) lock (b) completes
