Presumably.  An strace could verify the cause.

It's on the list of things to do but its relative priority and timing
hasn't been decided, as far as I know.  Unfortunately, doing it well it
requires some changes to the page fault paths in the kernel.  Nothing
serious, but that sort of thing always makes this kind of work take longer.

Not yet, no.
