This situation should not arise.

If the StoreEntry is locked, then the disk file won't be unlinked.

If the StoreEntry is unlocked, then the StoreEntry will be deleted
before the file is unlinked. So it won't be found by the
second client.

There might be other race conditions, but this is not one of them.
