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"...

  (gdb) p d
  $7 = 1091

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.
