Before this commit, in case FreeBSD libc jemalloc was overridden by another jemalloc, proper thread shutdown callback was involved only for the overriding jemalloc. A call to _malloc_thread_cleanup from libthr would be redirected to user jemalloc, leaving data about dead threads hanging in system jemalloc. This change tackles the issue in two ways. First, for current and old system jemallocs, which we can not modify, the overriding jemalloc would locate and invoke system cleanup routine. For upcoming jemalloc integrations, the cleanup registering function will also be redirected to user jemalloc, which means that system jemalloc's cleanup routine will be registered in user's jemalloc and a single call to _malloc_thread_cleanup will be sufficient to invoke both callbacks. |

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/
