Use only a stack of tasks for nosv

allow a nested task to execute when there are others in the stack.

...
These events only show if a thread has been removed from the CPU, but
doesn't provide information about what other thread caused the context
switch. This type of information can be obtained even with strict
/proc/sys/kernel/perf_event_paranoid settings.
