Problem: The boot(8) manpage currently describes the bootloader timeout logic to be
as if upon failure, it continuously attempts to reload the kernel with no upper bound
on the number of attempts. In the source code at sys/stand/boot/boot.c:150 the logic
dictates that only 2 attempts in total are attempted before giving up,
I have tested and verified this failure logic on my i386 system.

Solution: Fix the description on the manpage to emphasize that only a second attempt
is made in case the first attempt fails.
