May be hard to execute any kind of cleanup with new data added every second.
One theory for cleanup...
determine the line count, assuming each update is on its own line
divide that number in half
use a tail command to copy the 2nd half of the list to a new file
then copy it back to the original filename

svn_cleanup
SVN_CLEANUP(3) 1 SVN_CLEANUP(3)
svn_cleanup - Recursively cleanup a working copy directory, finishing incomplete operations and removing locks
SYNOPSIS
bool svn_cleanup (string $workingdir)
DESCRIPTION
Recursively cleanup working copy directory $workingdir, finishing any incomplete operations and removing working copy locks. Use when a
working copy is in limbo and needs to be usable again.
PARAMETERS
o $workingdir
- String path to local working directory to cleanup
Note
Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the
calling script's working directory, use realpath(3) or dirname(__FILE__).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
NOTES
Warning
This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in
a future release of PHP. This function should be used at your own risk.
EXAMPLES
Example #1
Basic example
This example demonstrates clean up of a working copy in a directory named help-me:
<?php
svn_cleanup(realpath('help-me'));
?>
The realpath(3) call is necessary due to SVN's quirky handling of relative paths.
