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.

liburcu-cds provides efficient data structures based on RCU and
lock-free algorithms. Those structures include hash tables, queues,
stacks, and doubly-linked lists.

Noteworthy:

There is a minor imperfection in the prior version (0.8.3/0.7.11)
corrected by this release. However, it is not required for
correctness. We are doing this release because clients will
base their packages (and did their testing) on those commits.

Changelog:
2014-03-08 Userspace RCU 0.8.4
        * Fix: move wait loop increment before first conditional block

2014-03-08 Userspace RCU 0.7.12
        * Fix: move wait loop increment before first conditional block
