I thought that the kernel hangs might be of interest.

The problem is your code.

int schedRc = pthread_setschedparam(t1, policy, &schedParam);

There is no guarantee that t1 is filled before you it here in the newly
created thread. Only when pthread_create() returns is the thread handle
guaranteed to be written.

Ah, that explains the error. I'm still trying to track down the kernel hangs though.
