I'd say all.  The glibc (libpthread) that does set*id across threads has
been in use for a while (2.3.4?), probably in distro's using kernels as old
or older than any active -stable streams.  In the race in question, this
kernel bug is breaking valid POSIX application expectations.


Thanks,
Roland
