If you look at the code, it's likely this bit:
M = self._column_ambient_module()
try:
vec = M(b)
except TypeError:
....
This means that a fresh copy of the vector "b" is always allocated. Getting
the memory would be most of the work, hence the higher "sys" time.
We could test if `b` has already the right parent and avoid the extra copy
in that case.
