    It seems like you can have a race condition here if you send the same 
handles to two different processes at the same time. If the second process 
finishes executing this and then the first process exits and sets the handles 
to uninheritable, then you would set uninheritable handles to the child 
process. If this function is supposed to have this behavior, maybe add a 
comment explaining that this function mutates the handles, so the caller needs 
to make sure to synchronize these calls.

    Hm, I remember we discussed something like `CreateProcessW` does process 
initialization async. Do we need to wait for the process to be initialized?
