While you may think its terribly inefficient, it isn't really. A fancy
"wait" function is just polling anyway, you're just making it overt.
You also have the ability to have proga and progb only touch the file if
they complete successfully. If you merely wait until their ps
disappears, you don't know if they crashed or properly completed.
