Here are some timings. In all these examples, `X = toric_varieties.dP8()`
and we consider `%timeit [X.cohomology_basis(1) for i in range(1000)]`.
The current `cachefunc.pyx` (using `_cache_key` in a try-finally-block):
{{{
1000 loops, best of 3: 419 µs per loop
}}}
The old version which does not handle unhashable objects at all:
{{{
1000 loops, best of 3: 387 µs per loop
}}}
The proposed implementation:
{{{
1000 loops, best of 3: 395 µs per loop
}}}
