pthread_key_create on QNX triggers recursive allocation during tsd bootstrapping. Using tsd_init_check_recursion to detect that. Before pthread_key_create, the address of tsd_boot_wrapper is returned from tsd_get_wrapper instead of using TLS to store the pointer. tsd_set_wrapper becomes a no-op. After that, the address of tsd_boot_wrapper is written to TLS and bootstrap continues as before. Signed-off-by: Jin Qian <jqian@aurora.tech>
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/
