I'm not sure if that would include locks on the file HANDLE.
hmmm. Doesn't seem like that would work, or that it makes sense. I'm guessing the bInheritHandle just makes the same handle available in the child process w/o having to reopen it (never used this feature). Locked regions are probably still owned by the parent.
