I use rtlevent, but only meant to maintain a pool of threads, while there
is no task for a thread it is blocked waiting for an event.
BUT, that cannot be used to prioritize a thread. While you block a thread
using rtlevent, it can only be unblocked from another thread. While you use
sleep(), it still get time share of the CPU, only that it does nothing
until sleep finishes, right? That way, it only consume a tiny amount of
computing power while sleeping. This, in my view, is the price I have to
pay to achieve my purpose?
