  Dont use KeyboardInterrupt to stop a build! [Issue 1907]

  SCons would often hang after pressing Ctrl-C. I started investigating and I
  realized that most of the Python libraries are not really safe with respect to
  asynchronous exceptions. Although,there are enough try/finally blocks to handle
  exceptions thrown synchronously by the library code, the Python libraries are
  not always protected against exceptions being thrown asynchronously, such as a
  KeyboardInterrupt being thrown at a completely random location.

  For example, the function Queue.empty() does not protect its mutex with a
  try/finally block. If the KeyboardInterrupt exception gets thrown while the
  mutex is held, any further attempt to access the Queue will lead to dead-lock
  (explaining why SCons hangs sometimes after pressing CTRL-C). Even the
  threading.Condition condition variables are not async-exception safe. It
  therefore seems a lost battle to try to stop a build by raising an exception.

  Instead, I have implemented a signal handler that tells the Jobs (and its
  associated Taskmaster) to stop the build. I have been careful to wait after the
  .sconsign file has been written back to re-install the default SIGINT signal
  handler that raises a KeyboardInterrupt exception.

  This patch is submitted against changeset 2773 of branches/core. The
  regression test suite has been run on RHEL4 using Pyhon 2.5.1 and
  1.5.2. My team has been using an SCons build with this patch for a
  while now on Windows, Linux and OSX.

  TestSCons.up_to_date() should use match_re_dotall

  I changed TestSCons.up_to_date() to use match_re_dotall instead of
  match_exact. This is necessary so that I can call up_to_date() with
  the TestSCons.deprecated_python_expr error message in one of my test.

  Note that TestSCons.not_up_to_date() is already using match_re_dotall.

  Ran the test suite on both Python 2.5.1 and 1.5.2.
