I'm just curious.

1. When we see FREEZING and have to retry ?
While there are some threads which wait for some event ?

2. What happens when FROZEN threads are moved to other group ?
Can we move them ?
Can we wake them up (if it can be moved) ?
What operations are allowed to frozen threads ?

Thanks,
-Kame
