Thanks.  Please remember that I have no experience with windows whatsoever.
I never heard of IO completion ports before (this shouldn't be a problem,
I can bite in a topic like a pitbul and in a month I should be an expert
in the field ;).

I asked my personal windows guru to give me an url about IO completion
Ports and he told me:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/i_o_completion_ports.asp

To my surprise, and possibly to your surprise as well ;), this starts as follows:

<quote>
I/O completion ports are the mechanism by which an application uses a pool
of threads that was created when the application was started to process
asynchronous I/O requests. These threads are created for the sole purpose
of processing I/O requests.

So... there we have our hidden threads!
Did you know this?
