1c4dd05f40 Add 126 to hardcoded stop exits
> If a command is not found, the exit status shall be 127. If the

> status shall be 126. Applications that invoke utilities without using

0d7303e75f Parse config later
This is just to keep the list of open file descriptors tidier, since
parsing the config creates many pipes.
