&gt; [ Re: double-buffering and non-blocking I/O ]
&gt; 
&gt; &gt;I could be wrong, but I wish it rest in piece - it was a performance
&gt; &gt;tuning nightmare. Either your I/O theread hogs all the resources looping
&gt; &gt;idle, waiting for the input, or it lags because of the wrong priority
&gt; &gt;set or bad timing.
&gt; &gt;
&gt; &gt;For me, the blocking I/O and a possibility to interrupt it (exceptions)
&gt; &gt;is a blessing.
&gt; &gt;
&gt; &gt;Comments, anyone?
&gt; 
&gt; Well, my comment would be that you've apparently only seen very
&gt; bad implementations of a perfectly reasonable technique.  When
&gt; the I/O thread has no more work to do, it should go to sleep,
&gt; to be awakened by the next I/O completion.  With proper signal
&gt; support, no busywait is needed, and bad timing is irrelevant
&gt; if you're acually getting the device notifications.

I guess we differ in the definitions, or rather I'm ignorant about ones.

Can you please give me a brief definition of a blocking and non-blocking
I/O?

The reason I ask is that I meant exactly what you said.
