They will exec, so no parent/child stuff. ionice will set the ionice setting then exec the next command. Likewise nice. There are plenty of little commands with this behaviour: make a setting change and then execute comething with the new setting: env etc. I've got a bunch of shell scripts with similar usage patterns as well. These "prefix" commands make a lot of simple things very easy to express in scripts.
