Additional information

This test is introduced in the commit 74b9baa

@RaisinTen
test: fix failure in test/sequential/test-heapdump.js
c6e4596 
The test was failing when it was being run with superuser privileges,
so this changes the test from attempting to write to a read-only file to
attempting to write to a file with the same name as that of an existing
directory, as that is a more reliable way of making
v8.writeHeapSnapshot() throw even when run with sudo.
