Well, my comment would be that you've apparently only seen very bad implementations of a perfectly reasonable technique. When the I/O thread has no more work to do, it should go to sleep, to be awakened by the next I/O completion. With proper signal support, no busywait is needed, and bad timing is irrelevant if you're acually getting the device notifications. - Alex </PRE> <!--X-Body-of-Message-End--> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <HR> <ul compact><li><strong>Follow-Ups</strong>: <ul> <li><strong><A NAME="00611" HREF="msg00611.html">[MUD-Dev] Re: lurker emerges</A></strong> <ul compact><li><em>From:</em> Vadim Tkachenko <vt#freehold,crocodile.org></li></ul> </UL></LI></UL> <!--X-Follow-Ups-End--> <!--X-References--> <UL><LI><STRONG>References</STRONG>: <UL> <LI><STRONG><A NAME="00607" HREF="msg00607.html">[MUD-Dev] Re: lurker emerges</A></STRONG> <UL><LI><EM>From:</EM> Vadim Tkachenko <vt#freehold,crocodile.org></LI></UL></LI> </UL></LI></UL> <!--X-References-End--> <!--X-BotPNI--> <UL> <LI>Prev by Date: <STRONG><A HREF="msg00609.html">[MUD-Dev] Re: lurker emerges</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg00611.html">[MUD-Dev] Re: lurker emerges</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg01053.html">[MUD-Dev] Re: lurker emerges</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg00611.html">[MUD-Dev] Re: lurker emerges</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="index.html#00610"><STRONG>Date</STRONG></A></LI> <LI><A HREF="thread.html#00610"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> <ul><li>Thread context: <BLOCKQUOTE><UL> <LI><STRONG>[MUD-Dev] Re: lurker emerges</STRONG>, <EM>(continued)</EM> <ul compact> <ul compact> <LI><strong><A NAME="00599" HREF="msg00599.html">[MUD-Dev] Re: lurker emerges</A></strong>, T.
