Jason Evans 14a2c6a698 Avoid validating freshly mapped memory. 
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).

README 

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.
