+"""#84185: a Windows gateway cold-started after update that dies immediately
+(e.g. a job object denying breakaway) must not be reported as started.
+
+``_cold_start_windows_gateway_after_update`` used to print the success line
+straight off a successful ``Popen`` return, which only proves the process was
+created, not that it survived. This asserts the observable output: the
+success line is gated on the process actually being found alive afterwards,
+same as every other ``_spawn_detached`` caller.
