Rewrite prof_alloc_prep() as a cpp macro, PROF_ALLOC_PREP(), in order to remove any doubt as to whether an additional stack frame is created. Prior to this change, it was assumed that inlining would reduce the total number of frames in the backtrace, but in practice behavior wasn't completely predictable. Create imemalign() and call it from posix_memalign(), memalign(), and valloc(), so that all entry points require the same number of stack frames to be ignored during backtracing.
jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a stand-alone "portable" implementation that currently targets 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/
