inode checkpoints

[Artem B. Bityuckiy]

Hello David, Josh. What did we decided about the GC thread?

I offered to create checkpoints from the GC thread. Are there some 
reasons not to do so? There was one - the GC thread isn't always 
enabled. But we may require it be enabled if checkpoints are enabled...

What do you think?

Or may be its better to use distinct thread ?

May be we create ICP during GC process, or on iget() call, or on iput() 
call? But I have arguments against these...

Are there some comments/advices?
