11 it seems that this binary is linked against the old linuxthreads glibc and fails
12 to allocate the thread stacks due to randomization, so just disable that one PaX
13 feature on it and it should work (as it apparently does) and also feel free to
14 tell the folding guys that it's time to move into the 21st century and switch to
15 nptl. at least that one doesn't want to allocate executable stacks.
