-Subject: [PATCH] Fix test_none_collisions on 32-bit systems
-
-There are two issues at play here:
-
-1. Python version of `map_hash` unnecessarily performs hash truncation
-   even if the hash is already 32-bit wide, which potentially converts
-   it from signed int to unsigned long.
-
-2. The `test_none_collisions` test generates a collision node with
-   hash greater than 2^32.
-
-Both of these are problematic on 32-bit systems, where `sizeof(Py_hash_t)`
-is 4, and so anything that doesn't fit into `Py_hash_t` gets bit-mangled,
-breaking the `hash(x) != x` invariance that the test relies upon.
-
-Fixes: #53
-Fixes: #50
