+# Having the test suite change behavior depending on the tests run makes
+# it extremely difficult to reproduce errors. I've also added a
+# "dbx_gdb_load" procedure. This and only this test will call these
+# procedures now. I also added an "expect" to the "send exec-file" line.
+# The "expect" waits for a prompt to appear. Otherwise, if the tests run
