 sorry to be a pain but i feel a need to clarify: is that most  definitely the case?

 to illustrate, which of these is true:

  • if i have two processes in a given domain, and one process runs the "drop privileges" selinux function, the process calling the function has its privileges "dropped" but the other process retains the _original_ privileges.
  • if i have two or more processes in a given domain, and one process runs the "drop privileges" selinux function, _all_ processes in that domain have their its privileges "dropped".
  • something indeterminate happens and it all goes pear-shaped.
