On any Unix system this is untrue.  Rotating a log file is quite simple:
simply rename the log file, then send a signal to the process to close
the log file handle and open a new one.  After that perhaps compress the
rotated log file.  Nothing is lost.  This is standard practice in Unix.
It is reliable.

Perhaps the scenario you posit would happen on Windows.
