Yes, but I'm talking about os.execvp, here. With the search in PATH.

I discovered that by accident while investigating another bug...

What is the bad idea? Keep looking in subsequent directories in PATH when you find a candidate for which execve() fails? Sorry, but I beg to differ, and POSIX is on my side.
