Improve error handling in goroutines

[xsachax]

In goroutines, we need to create a error channel and bubble errors outwards this way. We don't have proper handling of StartWithDebug goroutine

ex:

errCh := make(chan error)

go func() {
    if err := doWork(); err != nil {
        errCh <- err
        return
    }
    errCh <- nil
}()

if err := <-errCh; err != nil {
    // handle error
}
