Why do you need to extract the test's name from its command line?

+  proper = name
+  proper = filter(lambda x: not "--testing_serialization_file" in x, proper)
+  proper = filter(lambda x: not "--test" == x, proper)
+  proper = map(lambda x: string.replace(x, os.getcwd() + "/", ""), proper)
+  proper = string.join(proper[1:], "_")
+  return proper

No reason to measure execution time here. It is measured anyway and you can
fetch it from the testcase object. Which means you don't need any custom
behavior when a test starts, and can put everything into the progress
indicator's HasRun() method.

+
+    def finish(self, failed, failMsg = None):
+      elapsed = time.time() - self.starttime
+      self.root.attrib["time"] = str(round(elapsed,2))
+      if failed:
+        failure = xml.Element("failure")
+        failure.text = failMsg
+        self.root.append(failure)

In the new test driver, the progress indicators are no longer threaded, which
should make this class unnecessary (and some stuff below simpler).

+    def __init__(self):
+      self.curtest = None
+
+  def __init__(self, testName):
+    self.root = xml.Element("testsuite")
+    self.root.attrib["name"] = testName
+    self.local = UnitTestOutput.UnitTestLocal()
+    self.local.curtest = None
+
+  def startNewTest(self, name):
+    if self.local.curtest != None:
+      self.finishCurrentTest(False)
+    self.local.curtest = self.testCase(name)
+
+  def finishCurrentTest(self, newName, failed, failMsg = None):
+    if self.local.curtest != None:
+      self.local.curtest.finish(failed, failMsg)
+      if newName:
+        name = getProperTestName(newName)
+        self.local.curtest.root.attrib["name"] = name
+      self.root.append(self.local.curtest.getElement())
+    else:
+      sys.stderr.write("Tried to finish test but no test is active!")
+    self.local.curtest = None
+
+  def finishAndWrite(self, file):
+    if self.local.curtest != None:
+      self.finishCurrentTest(False)
+    xml.ElementTree(self.root).write(file, "UTF-8")
