Done. It "works".

Nope. Sitting in /tmp/rwp I run the program and the desired_depth is
computed to be 1091.

(gdb) p initial_cwd_len
$4 = 8
(gdb) p desired_depth
$5 = 1091

(gdb) p cwd
$6 = 0x6000000000004010
"/tmp/rwp/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B---/confdir-14B"...

The mkdir call never fails. It hits the desired depth and then cleans
up normally. It 'exit(0);'s at the end because fail = 3 was never hit.
