99% isn't 100%.
Sorry, but no, it can't happen, you can not for a process and end up with twice the memory requirements just because of the fork. What you can do is to simply allocate more memory than you were using before and keep writing.
The OOM killer is a nasty hack, it essentially moves the decision about what stays and what goes to a process that is making calls way above its pay grade, but overcommit and OOM go hand in hand.
