 Try running `circuitpadding_wronghop` in a loop, like this:
 {{{
 while ./src/test/test circuitpadding/circuitpadding_wronghop ; do true;
 done
 }}}

 After a minute or two it will fail with an error like this:
 {{{
   FAIL src/test/test_circuitpadding.c:1346: assert(n_client_cells OP_EQ
 2): 3 vs 2
 }}}
 or sometimes like this
 {{{
 circuitpadding/circuitpadding_wronghop: [forking]
   FAIL src/test/test_circuitpadding.c:1336: assert(n_client_cells OP_EQ
 1): 2 vs 1
 }}}
