What is prio_boost?

[DingWoonee]

I am modifying the FIFO example using the ghOSt framework to implement an O(1) scheduler, though I am not considering priority in this implementation.

Currently, the execution of "tests/simple_exp.cc" is freezing. In the FifoSchedule() function, when prio_boost is true, the LocalYield() function is called in the else block, causing the freeze. What is the role of prio_boost, and would it be okay to treat it as false and remove it?
