The 'gid' is the 'Grant ID' which identifies the group this grant belongs to.
What this means is that every record in the node_access table grants privileges
(either view, update or delete) to the node to anyone with that grant ID.
What the Grant ID really means is completely up to the realm that's using it.
In the case of taxonomy access (which uses the term_access realm), a GID maps
directly to an RID, which is a Role ID, and is one of the most common
groupings. But for something like OG, the GID is a NID which points to the
organic group node that represents the group. Other modules could have other
ways to group users together.
