Why reinvent the wheel again ?

Since Amdahl wrote the book on this as recently as 1967, it is no wonder that we old pharts have not caught on to the tricks of multithreading yet. I must confess that I actually wrote a single-threaded program only ten years ago.

Isn't this multi threading getting a little old? And the comments to GA ( Gene Amdahl ), mainframes, etc. Sorry to tell but the multi tasking ( better than multi threading IMHO ) and multi threading are definitely nothing new. Yes, I know a lot of programmers didn't get any exposure because of the PC ( and other microprocessors ) but it is no excuse except for bad education. Maybe someone remembers what "TASK" and "ATTACH", etc did on AP/MP processors, how channel attached systems did work and I'm not even talking about separate, asynchronous memory and I/O processors which were standard issues since 70's ( and some even earlier ).
