actually.. switching from one "real" thread to another in Linux is not
an actual context switch in the hardware sense... at least this part of
your argument seems to be incorrect ;)
How does that work? Switching between kernel threads requires going into
the kernel, user level thread switches are all done in user mode.
Do you have some way to change o/s threads w/o going into the kernel?
