ResourceUseList::add is called repeatedly when we need to
track a resource's usage in a context. Instead of a
potential memory operation on each add we reserve memory
upfront for about 4k SharedResourceUse objects. If the
vector grows larger, it will be automatically handled by
std::vector's allocator.
