==8214== TO CONTROL THIS PROCESS USING vgdb (which you probably
==8214== don't want to do, unless you know exactly what you're doing,
==8214== or are doing some strange experiment):
==8214==   /usr/lib/valgrind/../../bin/vgdb --pid=8214 ...command...
==8214==
==8214== TO DEBUG THIS PROCESS USING GDB: start GDB like this
==8214==   /path/to/gdb test/memory_leak.js
==8214== and then give GDB the following command
==8214==   target remote | /usr/lib/valgrind/../../bin/vgdb --pid=8214
==8214== --pid is optional if only one valgrind process is running
