+// This is the bit that runs in the parent process when the test begins. Here's
+// what happens:
+//
+//  - Load the entire single-process test in the parent
+//  - Setup the test harness within the child process
+//  - Send a command to the child to have the single-process test loaded there, as well
+//  - Send a command to the child to make the predictor available
+//  - run_test_real in the parent
+//  - run_test_real does a bunch of pref-setting and other fun things on the parent
+//  - once all that's done, it calls run_next_test IN THE PARENT
+//  - every time run_next_test is called, it is called IN THE PARENT
+//  - the test that gets started then does any parent-side setup that's necessary
+//  - once the parent-side setup is done, it calls continue_<testname> IN THE CHILD
+//  - when the test is done running on the child, the child calls predictor.reset
+//    this causes some code to be run on the parent which, when complete, sends an
+//    obserer service notification IN THE PARENT, which causes run_next_test to be
+//    called again, bumping us up to the top of the loop outlined here
+//  - when the final test is done, cleanup happens IN THE PARENT and we're done
+//
+// This is a little confusing, but it's what we have to do in order to have some
+// things that must run on the parent (the setup - opening cache entries, etc)
+// but with most of the test running on the child (calls to the predictor api,
+// verification, etc).
