Fix management of extent_grow_next to serialize operations that may grow retained memory. This assures that the sizes of the newly allocated extents correspond to the size classes in the intended growth sequence. Fix management of extent_grow_next to skip size classes if a request is too large to be satisfied by the next size in the growth sequence. This avoids the potential for an arbitrary number of requests to bypass triggering extent_grow_next increases. This resolves #858.
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, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. 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. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://jemalloc.net/
