Create more threads with less stack space
default stack size is 10M. This makes your multithread app filling rapidly your memory. on my PC I was able to create only 300thread with default stack size. Lower the default stack size to the one effectively used by your threads, let you create more. ex. putting 64k I was able to create more than 10.000threads. Obviously ...your thread shouldn't need more than 64k ram!!!

Archive a directory with datestamp on filename
A useful bash function: gztardir() { if [ $# -ne 1 ] ; then echo "incorrect arguments: should be gztardir " else tar zcvf "${1%/}-$(date +%Y%m%d-%H%M).tar.gz" "$1" fi }
