It's actually able to do a decent job. The problem at hand is not
due to the "kernel bug", but rather the lack of unwind information
for the pthread_cond_wait() function.
And I am afraid that pthread_cond_wait() is just one example. With
GCC getting better and better at optimizing, we will likely see
this more and more often...
