Exercise 1
Idle-waiting Thread Joining
– It have as an objective to change the method “join” of a Thread. It was implemented like this:

[code lang=”c”] while(_state != FINISHING)
yield();
[/code]

This method consist in verify the state of the Thread that is joined, if the state is different from FINISHING, it calls yield(). This solution cause an overhead, because it do this verification all the time that the process is Phased. We should implement a new function, that don`t cause this overhead.

Modified files:
– thread.cc
– Thread.h
