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

 

cd src

yum -y install tcl    //提示缺这玩意

make test  //这里执行了2次，不知道为什么，但是都是按照提示来的，直到出现下面界面

167 seconds - integration/replication

172 seconds - integration/replication-psync
