Possible fix to issue #45.

Hi,
Thanks for the PR but I preferred another approach.
you can see in this commit.

In general, it has the same purpose of your change - dropping events if reaching a limit. But here I'm using the BulkSize as the limit and let the background timer to do the actual logging.

I will publish this in the next version - will be false by default
