The MPEG audio format is built with frames, which encompass a fixed number of samples/fixed amount of time (depending on channels/sampling rate/...). What you're seeing looks like a consequence of this. However, as far as I know lame puts an extra header into the file, which includes - among other more or less interesting values - the exact number of "valid" samples. This could be used by players/other programs to determine the length. Obviously, the program you checked the length with does not take this into account. Alas, I do not know at all which programs do so.
