Once the file is locked it should, under proper programming, be locked to a write function. It should remain open to a read call but past that I cannot fathom a data corruption in this instance. If the programmer of the application properly coded the program and the first user opened the file to write function, and created the lock call, this would force the handle closed to write therefore causing user two no access. In some instances this could happen if the write calls were exactly simultaneous but that has a probability of about a million to one.
