// 1. readdir
// 2. for each entry
//   a. if a non-empty directory, recurse
//   b. if an empty directory, move to random hidden file name in $TEMP
//   c. unlink/rmdir $TEMP
//
// This works around the fact that unlink/rmdir is non-atomic and takes
// a non-deterministic amount of time to complete.
//
// However, it is HELLA SLOW, like 2-10x slower than a naive recursive rm.
