This is very difficult:

  There is no safe way to abort a thread without its help -- an
  the thread might be in a condition where it does not recognize
  that its help is needed (e.g. it is waiting in a C extension).

With version 2.3, Python grew a C-level (!) API function which
sends an exception to a thread. In case, the thread is executing
Python code, this exception may abort the thread (cleaning us as
usually). However, when the thread executes C code, the exception
is not seen until it reenters the Python interpreter.
Therfore, this is only a partial solution...
