make MALLOC=libc
==========================================================
To force compiling against libc malloc, use:
% make MALLOC=libc
To compile against jemalloc on Mac OS X systems, use:
% make MALLOC=jemalloc
分配器allocator，libc 并不是默认的 分配器， 默认的是 jemalloc, 因为 jemalloc 被证明 有更少的 fragmentation problems 比libc。
=======================================================================
make MALLOC=libc
