* the simple version of SkipList.
* for multi-thread safe purpose, we employ pthread_rwlock_t to guarantee to generate

* enhance the performance. In this case, one should use the concurrent skip list (by
* using michael-scott algorithm) instead of this simple version in a multi-thread
* environment, to achieve higher performance of read/write operations.
*
* Note: Duplicated primary key situation.
* In case of duplicated primary key, two ways can be employed to handle this situation:
* 1. add as normal insertion with out special process.
* 2. add an overflow pointer at each list node, all nodes with the same key will be added
* in the overflow pointer. In this case, the total steps of each search will be reduced significantly.
* Currently, we implement the skip list in a line with the first means, maybe refactor it soon.
*
* Memory consumption: the memory alignment causes many memory wasted. So, employ a memory
* pool will significantly reduce the total memory consumption, as well as the calloc/malloc operation costs.
*
* 3. use the iterator pattern to refactor all routines to make it more clean
