123 * \- first child (via fork()) is the pokee
124 * \- second child (via g_test_trap_fork()) is the poker
126 * The second child only exists to avoid sharing a main context between several
127 * second-children if we run a test resembling this one multiple times.
128 * See https://bugzilla.gnome.org/show_bug.cgi?id=658999 for why that's bad.
