    Assert threads are created in test 642026
    
    We kept seeing the glib testsuite hanging on our CI system in the
    testcase for 642026. After some digging it turned out the jenkins slave
    was misconfigured and its task limit was too low.
    
    Add an assertion that the test thread has been created to more easily
    spot this error condition as opposed to the test simply hanging.
