Add support for blocked commands in isolationtester This enables us to test that blocking commands (such as foreign keys checks that conflict with some other lock) act as intended. The set of tests that this adds is pretty minimal, but can easily be extended by adding new specs. The intention is that this will serve as a basis for ensuring that further tweaks of locking implementation preserve (or improve) existing behavior. Author: Noah Misch

CREATE TABLE parent (
parent_key int PRIMARY KEY,
aux text NOT NULL

child_key int PRIMARY KEY,

INSERT INTO parent VALUES (1, 'foo');
}
teardown
{
DROP TABLE parent, child;

session "s1"
Set different deadlock_timeout on each session in new isolation tests This provides deterministic deadlock-detection ordering for new isolation tests, fixing the sporadic failures in them. Author: Noah Misch

## Most theoretical permutations require that a blocked session execute a
