'mysqbinlog' tool creates a temporary file while 
preparing LOAD DATA QUERY. These files needs to be deleted
at the end of the test script otherwise these files are
left out in the daily-run machines, causing
"no space on device issues"
      
Fix: 
Delete them at the end of these test scripts
1) execute mysqlbinlog with --local-load option to
create these files in a specified tmpdir
2) delete the tmpdir at the end of the test script
