XC_VM_Fanout's interop harness runs MAIN's PHP as many processes over
one database. Since the unit suite moved to MariaDB, every TestDb opened
a throwaway schema of its own and dropped it with the instance, so the
harness could not share MAIN's state and every panel-backed agent test
failed at its setup.
new TestDb('xcvm_t<pid>_<n>') opens that schema, creating it when
missing, and no instance drops it. Named after a process that outlives
the others (the Go test), TestDb's orphan cleanup drops it once that
process has ended. ADR 0004's note on the interop test says it runs
again.
