==76484== TO CONTROL THIS PROCESS USING vgdb (which you probably
==76484== don't want to do, unless you know exactly what you're doing,
==76484== or are doing some strange experiment):

==76484==
==76484== TO DEBUG THIS PROCESS USING GDB: start GDB like this
==76484== /path/to/gdb ./42sh
==76484== and then give GDB the following command
==76484== target remote | /Users/nmeier/.brew/Cellar/valgrind/3.12.0/lib/valgrind/../../bin/vgdb --pid=76484
==76484== --pid is optional if only one valgrind process is running
