+liburcu is a LGPLv2.1 userspace RCU (read-copy-update)
+library. This data synchronization library provides
+read-side access which scales linearly with the number
+of cores. It does so by allowing multiples copies of a
+given data structure to live at the same time, and by
+monitoring the data structure accesses to detect grace
+periods after which memory reclamation is possible.
