ISC groups are POSIX groups which are the same as BSD groups.  However,
to use ISC groups, each program must be compiled to use the POSIX universe.

I don't know why ISC didn't just make that the standard behavior.

For normal users/programs you need to run newgrp, which is like su in that
it spawns a new shell with the new group id, but the old shell is gone and
you would need to do another newgrp to go back.

Yes.

Nope.
