19// PROOF selector for I/O benchmark test. //
20// For I/O benchmark, event files are read in and histograms are filled.//
21// For memory clean-up, dedicated files large enough to clean up memory //
22// cache on the machine are read in. Or memory clean-up can be //
23// accompolished by system call on Linux machine inside SlaveBegin(..) //
24// which should be much faster the reading in large files. //
