Issue Type: Improvement
Affects Versions: 2.0.0-alpha, 0.23.0, 3.0.0

Token operations unnecessarily obtain the write lock on the namespace. Edits
for token operations are independent of edits for other namespace write
operations, and the edits have no ordering requirement with respect to
namespace changes.
