Mike Hommey 6505733012 Make opt.lg_dirty_mult work as documented 
The documentation for opt.lg_dirty_mult says:
    Per-arena minimum ratio (log base 2) of active to dirty
    pages.  Some dirty unused pages may be allowed to accumulate,
    within the limit set by the ratio (or one chunk worth of dirty
    pages, whichever is greater) (...)

The restriction in parentheses currently doesn't happen. This makes
jemalloc aggressively madvise(), which in turns increases the amount
of page faults significantly.

For instance, this resulted in several(!) hundred(!) milliseconds
startup regression on Firefox for Android.

This may require further tweaking, but starting with actually doing
what the documentation says is a good start.

README 

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, Valgrind integration, 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.
