Because there is (currently) zero or one file descriptor per easy handle, so
you need an array that fits the same number of descriptors as number of easy
handles. It could be many. (Of course we also want to allow more than one
descriptor per handle, should the need arise in the future.)

I want libcurl to "own" the memory for the arrays, since then libcurl can keep
the arrays around for the next call and it won't have to realloc() arrays that
already have a proper size. Which in real life will mean that for most calls
to this functions, there will be no malloc() or realloc() needed.

To me, that seems like more overhead and complexity for an app. You would
typically call this curl-function every time you want to do select() or
poll().
