Since these are all GdbRemote tests, the regular process of iterating over targets/process in self.dbg and killing them is ineffective. I think we'll need to add a tear down step in gdbremote_testcase.py to cleanup using raw gdb packets to debugserver.
all processes get re-parented to launchd and they *remain zombies there*. That is horrifying. This cannot possibly be the intended behavior.
