resize_nthreads!(A, copyvalue=A[1])
Resize the array `A` to length [`nthreads()`](@ref). Any new
elements that are allocated are initialized to `deepcopy(copyvalue)`,
where `copyvalue` defaults to `A[1]`.
This is typically used to allocate per-thread variables, and
should be called in `__init__` if `A` is a global constant.
