This means # that any kernel running on a box with more than 4096 threads (NR_CPUS # advertises a limit of of 8192 cpus) would expose userspace to two cpu # contexts running at the same time with the same cpu number. # # Note: I'm not aware of any distro shipping a kernel with support for more # than 4096 threads today, nor of any system image that currently exceeds # 4096 threads.
