Remove mmap_unaligned, which was used to heuristically decide whether to optimistically call mmap() in such a way that could reduce the total number of system calls. If I remember correctly, the intention of mmap_unaligned was to avoid always executing the slow path in the presence of ASLR. However, that reasoning seems to have been based on a flawed understanding of how ASLR actually works. Although ASLR apparently causes mmap() to ignore address requests, it does not cause total placement randomness, so there is a reasonable expectation that iterative mmap() calls will start returning chunk-aligned mappings once the first chunk has been properly aligned. |

jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a stand-alone "portable" implementation that currently targets FreeBSD, Linux and Apple OS X. jemalloc is included as the default allocator in the FreeBSD and NetBSD operating systems, and it is used by the Mozilla Firefox web browser on Microsoft Windows-related platforms. Depending on your needs, one of the other divergent versions may suit your needs better than this distribution. 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://www.canonware.com/jemalloc/
