>From what I understand, an Argobots execution stream is mapped to a
pthread, and the ULTs are executed by it. What happens when there is no ULT
in the ES, does the pthread sleep and wait on a conditional variable until
a new ULT is scheduled for execution? Does it compete with other
non-Argobots threads for the CPU resources while idle?
