I completely agree with you. If we can roll back time, we should fix
to return tid because current implementation is POSIX invalid (*).
however it's impossible and making new interface for getting tid is
best practical solution.

(*) pthread_kill() must return -ESRCH if target thread was already
exited. that imply
    pthread_self() returns pid like id number, not bare C pointer.
