That's simply not true. You can sleep for less than a jiffy. See my edit.

... and trigger an immediate wakeup for your process. What's your point? Sure, if you have a higher priority process also running then the scheduler might decide that the other process gets to run instead of you, but that's always a problem on a multitasking operating system, and can be solved with appropriate application of SCHED_RR, SCHED_FIFO, priorities, etc.

The kernel could do that, yes, but it doesn't, nor does it provide any way for you to get at that data from outside the kernel. You could change the kernel, of course.

comment How to see the commands executed in another shell?
It's open source; you could always add that feature if you really need it. :) Or add a slightly more intelligent script parsing the strace output that ignores a PID once it execs.
