Idan Horowitz 1d96c30488 Kernel: Stop leaking leftover committed cow pages from forked processes 
Since both the parent process and child process hold a reference to the
COW committed set, once the child process exits, the committed COW
pages are effectively leaked, only being slowly re-claimed each time
the parent process writes to one of them, realizing it's no longer
shared, and uncommitting it.
In order to mitigate this we now hold a weak reference the parent
VMObject from which the pages are cloned, and we use it on destruction
when available to drop the reference to the committed set from it as
well.
