--- Comment #10 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
I meant the updated gnulib version from its repository, not the outdated
version glibc packs now.  The gnulib version currently does not use neither the
process pid nor the clock for source of entropy, it uses either getrandom or a
simple linear congruential generator if getrandom fails.

I think using getentropy where available should make it more robust. These
interface contains inherent concurrent issues and applications should either
use O_TMPFILE or at leat tmpfile.
