As I understand it, a conservative garbage collector works
by checking the stack for any pointer like words, and assuming
these root collectable objects.
What happens in a system like Windows when the user gives away
the object addresses to the operating system, so for most
objects there are no roots on the stack, because the stack
is empty most of the time?
[The object pointer is stored in Window memory, owned by the OS,
by the object is on the heap as usual.]
Wouldn't this mean GC would have to be carried out at the OS level?

user level GC to see the OS's pointers into its address space. -John]
