Move validation of supposedly zeroed pages from chunk_alloc() to chunk_recycle(). There is little point to validating newly mapped memory returned by chunk_alloc_mmap(), and memory that comes from sbrk() is explicitly zeroed, so there is little risk to assuming that chunk_alloc_dss() actually does the zeroing properly. This relaxation of validation can make a big difference to application startup time and overall system usage on platforms that use jemalloc as the system allocator (namely FreeBSD). Submitted by Ian Lepore <ian@FreeBSD.org>.
jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a "portable" implementation that currently targets FreeBSD, Linux, Apple OS X, and MinGW. 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/
