	I always thought UNIX checked in the directory you are in first
	for the binary, then if it couldn't find it there, it checked
	the $PATH.

Absolutely not!!!  The algorithm is a function of the shell, but all shells
I know of use $PATH only.  If "." is not in $PATH, then commands in the
current directory must be executed using "./foo" or something similar.
