Add the 'M' and 'm' MALLOC_OPTIONS flags, which control the maximum medium size
class.
Relax the cap on small/medium run size to arena_maxclass.
Reduce arena_run_reg_dalloc() integer division code complexity.
Increase the default chunk size from 1MiB to 4MiB.
implementation, calls free() after calling TSD destructors. This was causing a
crash during thread exit, since the magazine rack was no longer valid for the
thread. Fix this by using a special mag_rack value to indicate that
deallocation should bypass the magazine machinery.
jemalloc is configured.
Modify arena_malloc() API to avoid unnecessary choose_arena() calls. Remove
unnecessary code from choose_arena().
Enable lazy-lock by default, now that choose_arena() is both faster and out of
the critical path.
Implement objdir support in the build system.
Implement minimal Makefile.
Make compile-time-optional jemalloc features controllable via configure
options (debug, stats, tiny, mag, balance, dss).
Conditionally exclude most of the opt_* run-time options, based on configure
options (fill, xmalloc, sysv).
Implement optional --enable-dynamic-page-shift.
Implement optional --enable-lazy-lock.
Re-order malloc_init_hard() and use the malloc_initializer variable to support
recursive allocation in malloc_ncpus().
Add mag_rack_tsd in order to receive notifications of thread termination.
Add jemalloc.h.
