Yes, but it's not really a "special" OS. Most linux systems are configured like
that by default, where you're only allowed to debug your own children (unless
they explicitly allow that, or you're root, etc.). Check out
https://www.kernel.org/doc/html/v4.15/admin-guide/LSM/Yama.html.
lldb_enable_attach is our own invention, which calls the appropriate os
interface to enable attaching if necessary. Currently, it's only implemented on
linux.
