   * Perform a small read on every file in a directory tree.
   *
   * Useful for testing file systems like proc, sysfs and debugfs or anything
   * which exposes a file like API so long as it respects O_NONBLOCK. This test
   * is not concerned if a particular file in one of these file systems conforms
   * exactly to its specific documented behavior. Just whether reading from that
   * file causes a serious error such as a NULL pointer dereference.
   *
   * It is not required to run this as root, but test coverage will be much
   * higher with full privileges.
   *
   * The reads are preformed by worker processes which are given file paths by a
   * single parent process. The parent process recursively scans a given
   * directory and passes the file paths it finds to the child processes using a
   * queue structure stored in shared memory.
   *
   * This allows the file system and individual files to be accessed in
   * parallel. Passing the 'reads' parameter (-r) will encourage this. The
   * number of worker processes is based on the number of available
   * processors. However this is limited by default to 15 to avoid this becoming
   * an IPC stress test on systems with large numbers of weak cores. This can be
   * overridden with the 'w' parameters.
