While kmhash is resizing, the number of mutex lock instance is also increased because each bucket of kmash has an instance of mutex lock. On windows, this leads to too many open mutex lock error, causes segfault.
Solution: shared mutex lock instance between kmhash buckets.
(Maybe) better solution: get rid of mutex lock on inner umi hash tables.
