> Now, Tick is Concurrent GC implementation in Harmony, I improve it in 3 ways:
> 1, State-based synchronization of mutators and gc collectors.
> 2, improve the concurrent gc scheduler
> 3, fix some bugs, one is the bug for array copy, so the vmcore module should be updated also.
> it has 18% performance speedup compared with original implementation.
> later I will upload a more detail description for this issue.
