I happend to enjoy MVCC a little in (v6.4.1) .

Readers are never blocked and writers are blocked only by 
same row writers as I expected.
It's so comfortable.

But I have a question.
Once transactions are blocked,it takes so long time to resume 
after blocks were removed.
Why ?
Currently blocked transactions resume immediately after blocks 
were removed.
