Module did not self-register: Worker Threads about pprof-nodejs

[theanarkh]

I think we can not use pprof in both the main thread and the worker thread, but we can use it in worker thread as follows.

const { Worker, isMainThread } = require('worker_threads');
// Can not be loaded in both the main thread and the worker thread
// const profile = require('pprof');

if (isMainThread) {
    new Worker(__filename)
} else {
    const profile = require('pprof');
    // Removing this will cause a crash
    process._stopProfilerIdleNotifier = process._startProfilerIdleNotifier = () => {};
    profile.time.profile({
        durationMillis: 1000,
    });
}

1. node_modules/pprof/profiles.cc I have changed NODE_MODULE(google_cloud_profiler, InitAll); to NAN_MODULE_WORKER_ENABLED(google_cloud_profiler, InitAll);
2. cd node_modules/pprof/build && make
3. as @theanarkh said before calling profile I've added this line process._stopProfilerIdleNotifier = process._startProfilerIdleNotifier = () => {};

Worker profiling totally working now
