I guess they were hinting at scheduling issues where there are many more goroutines than kernel threads available. Not a problem for Web services and applications but a potential problem for hard real-time. I don't think 12.0, 1.1, 1.2,… will change the core issue – though it will change the code generation, which is getting better. Though gccgo already produces very efficient code, much faster execution than the main Go system. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
