Hm, does this mean it ignores win32 file locking? By that I mean files are locked against deletion while a handle to them is held open, unlike on posix systems

Hm, does this mean it ignores win32 file locking? By that I mean files are locked against deletion while a handle to them is held open, unlike on posix systems where you can rm an open file and it just unlinks it from the filesystem without deleting the data (until the refcount goes to zero). The level of damage described sounds like it does.
