This is a total hack and shouldn't be required, but you could try adding
a call to unlink after the close() in MainServer::TruncateAndClose().

Look in mainserver.cpp and search for the following line at the bottom
of the TruncateAndClose() method.

	bool ok = (0 == close(fd));

Add a couple lines right after that like this:

	bool ok = (0 == close(fd));

	if (ok)
	    ok = (0 == unlink(filename));

It could be that a broken SMB implementation is keeping the file around
even though we deleted it because of the fact that we continued to
access the file by truncating it.  This will forcibly delete the file
after we've truncated it down as far as we wanted.
