Summary: This call is used to continue execution when the app has just been started in a "wait for debugger" mode. This is the only case in which it has an effect. Notably, it should do nothing in the following cases, which a layperson may be tempted to classify as "WaitingForDebugger": * The app was running detached and hit a 'debugger;' statement * The app is paused because of a breakpoint or hitting the Pause button * The app stopped on an instrumentation breakpoint, and expects the debugger to collect data and potentially auto-resume.
