20 | # On HP-UX 11.0, this test is causing a process running | |
21 | # the program "attach" to be left around spinning. | |
22 | # Until we figure out why, I am commenting out the test | |
23 | # to avoid polluting tiamat (our 11.0 nightly test machine) | |
24 | # with these processes. RT | |
25 | # | |
26 | # Setting the magic bit in the target app should work. | |
27 | # I added a "kill", and also a test for the R3 register | |
28 | # warning. JB | |
