The thread library maintains an internal list of threads. If you've
cloned the process, without telling the C library about that, you're
going to end up with the same list of threads; so the behavior you
describe is not surprising.

Not really. You might be able to preload a dummy libthread_db.so.1
that always failed to detect new threads.
