(description "liburcu is a user-space @dfn{Read-Copy-Update} (RCU) data
synchronisation library. It provides read-side access that scales linearly
with the number of cores. liburcu-cds provides efficient data structures
based on RCU and lock-free algorithms. These structures include hash tables,
queues, stacks, and doubly-linked lists.")
