Comment (by merijn):

 FWIW, the original test was...rather hacky to begin with. It was basically
 relying on the test-suite terminating the job after X seconds and
 producing a timeout, since the original bug caused that program to
 immediately crash. So prime suspects would be any change in the timeout
 mechanism of the testsuite producing a different error code.

 Also, if T8089 terminates when you run it on the commandline something is
 *obviously* wrong as that program shouldn't exit until, approximately
 292,471 years after starting.
