This should be gr.sync_block. gr.gr_sync_block is actually the swigged
representation of the c++ class, and I dont think it should be there. Oh

Also, to get this feature you will need to install my next branch or
python_blocks branch. Sorry, writing blocks in python is not a mainline
feature. I hope someday it will be accepted.
This is my git repo with said branches:
