-# Shells and the file descriptors they reserve for the user:
-#   * Debian Almquist Shell
-#     - The shell doesn't understand any file descriptor greater than 9.
-#     - File descriptors starting at 10 are used for I/O redirection.
-#   * BusyBox ash
-#     - File descriptors starting at 10 are used for job control and I/O
-#       redirection.
-#   * GNU Bash:
-#     - GNU Readline uses file descriptor 255 in interactive shells.
-#     - File descriptors starting at 10 are used for I/O redirection.
-#   * MirOS Korn Shell
-#     - File descriptors starting at either 10 or 24 are used for the shell's
-#       tty_fd and shl_dbg_fd.
-#   * Solaris ksh
-#     - The shell doesn't understand any file descriptor greater than 9.
