This can be avoided if the array is pinned, using GetPrimitiveArrayCritical, but currently there's no way for JNA to signal that an array should be handled that way - and we shouldn't do all arrays as pinned, since Get*ArrayCritical locks the GC until the corresponding Release*ArrayCritical is called - v.bad for native methods that might block.

Other than the obvious aspect of the array itself being GC'd, why would a pinned primitive array interfere with GC?
