Implement swtch() for x86 and arm (or whatever cpu you have). This is if you want to be a systems programmer, work on operating systems, file systems, etc. There is something magical about calling a function as one process and returning as another. I did this while still at school for Udi Manber (agrep, google search vp) because he wanted a user level threads package. You can see my hacky code for the VAX (I think) at http://www.mcvoy.com/lm/T/src/Tasm.S http://www.mcvoy.com/lm/T/src/Tasm.S http://www.mcvoy.com/lm/T/src/Tswitch.c http://www.mcvoy.com/lm/T/src/Tswitch.c it's from 1987 when I was a grad student, probably doesn't compile.
