+jemalloc is a general purpose malloc(3) implementation that emphasizes
+fragmentation avoidance and scalable concurrency support.
+
+jemalloc first came into use as the FreeBSD libc allocator in 2005.
+In 2010 jemalloc development efforts broadened to include developer support
+features such as heap profiling, Valgrind integration, and
+extensive monitoring/tuning hooks.
+Ongoing development efforts trend toward making jemalloc among the best
+allocators for a broad range of demanding applications, and
+eliminating/mitigating weaknesses that have practical repercussions
+for real world applications.
