It doesn't sound like the thread is communicating with the process
much.  Therefore:

1. Run the C code in a separate process, or
2. Create the thread from a C extension, maybe even straight from
ctypes, and kill it from C or ctypes.

Arguing that there are good reasons to allow killing threads isn't
going to get you very far.  The language developers already know
killing a thread is useful, yet the disallowed it anyway.  The
drawbacks were judged too severe (it makes enforcing invariants pretty
much impossible).
