> Stats trap in threads created by spawn_event_threads() and spawn_thread()

>
> There are two ways to create threads in ATS:
> 1) By EventProcessor::spawn_event_threads(), such as ET_NET threads.
> 2) By EventProcessor::spawn_thread(), such as flush thread.
> But I found that we can't stats the same things across these two type of
> threads.
> For example, I used the following statement in _checkout_write() to do stats
> before add to flusher queue:
> {code}
> LogBuffer *
> LogObject::_checkout_write(size_t * write_offset, size_t bytes_needed) {
> ...
> LOG_SUM_DYN_STAT(log_stat_bytes_add_to_flush_queue,
> buffer->header()->byte_count);
> m_buffer_manager[idx].add_to_flush_queue(buffer);
> Log::preproc_notify[idx].signal();
> ...
> }
> {code}
> As _checkout_write() function will be executed at ET_NET threads and flush
> thread, the stats value will be incomplete -- the value collected in flush
> thread will not be merged into the final result.
