Yes, I did too; the intent is that pthread_create is supposed to
return failure on kernels where things are not going to work right
(i.e. clone does not support the necessary flags to provide threads);
this is in turn supposed to result from a failure in pthread_self.
Could you provide the output of running the program under strace on
2.4?
