Swap out to disk - sorry I thought that was implicit
There's no disk on some devices. Anyway, that's up to the OS.
Advisory calls could help but we need some real examples, or better:
evidence from real apps, before inventing advice APIs here.
Also obj.kill() would be almost [im]possible to actually implement
since
what would happen if you happen to kill an object that still has
references somewhere?
I would say the killed object would just equate to 'null'
Then set obj = null.
If a programmer kills an object and then tries to reference it, then
that's his/her problem
No. You're ignoring the possibility of other references:
obj = frobj = gobj = new Object; ...; obj.kill()
How what happens when frobj or gobj is used?
I would assume the work involved in going through every DOM and script
object and working out whether they are islands is non-trivial,
whereas
de-allocating the actual memory for the resulting object list would
be.
See above -- you can't assume there are no other references to that
memory. Each variable or property that can be assigned anywhere that
could connect to obj (the object, not the reference) could save a ref.
