Holy Race Condition, Batman! Never mind the system call, this is a recipe
for disaster as written. You run the risk of new data being written at
the wrong time or total loss of data if two of these run at the same time.
I would highly, highly, highly suggest either using a log rotation tool
(such as logrotate) or a manual process to move the files.
Is there any particular reason you need a cyclical log file instead of
one that grows?
