Hitting libcuckoo_load_factor_too_low when inserting large amount of data in parallel #93

Hi, did I do something wrong? Or is this a known limitation of libcuckoo? regards.

This exception is intended to be thrown in degenerate circumstances, where the table is resizing way more frequently than expected (leading to a load factor of less than 5%). Most often, the culprit is a suboptimal hash function, which fails to distribute the keys over the entire table.

Happy to take a look if you could post a code snippet.
