Schlufi 55a7738837 AK: Use a full-period xorshift PRNG for double_hash 
The previous implementation had some pretty short cycles and two fixed
points (1711463637 and 2389024350). If two keys hashed to one of these
values insertions and lookups would loop forever.
This version is based on a standard xorshift PRNG with period 2**32-1.
The all-zero state is usually forbidden, so we insert it into the cycle
at an arbitrary location.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

You can watch videos of the system being developed on YouTube:
