https://unix.stackexchange.com/a/644209 seems quite interesting, since (modern) containers run in separate Linux namespaces.

We should probably also formulate and document a (htop) definition of container: - a curated list of supported container engines (docker, lxc, podman, ...) - usage of Linux kernel features...

Linux namespaces can be distinguished by their id from the inode number of `/proc//ns/pid`; but that file is unfortunately only readable by root.

An alternative might be to test a set of signal IDs for availability, e.g. via `sigaddset(3)`, and then use the ones not returning EINVAL with the name from `strsignal(3)`.

Since the handling of hugepages is Linux only, maybe the new setting should also be only available on Linux.

Should be fixed with https://github.com/EstebanBorai/local-ip-address/pull/108/commits/63652700de463c25cea00800eb38d3343310a2dd

While rerunning the benchmark I did not notice a significant time saving anymore. Maybe the simplification of `myglob()` made this obsolete.
