Original commit message:

Stop profiler on isolate teardown if still running If the profiler is started via the API and not stopped, V8 will intermittently crash during isolate teardown. The fix is to run the DeleteAllProfiles function in Isolate::Deinit() if cpu_profiler_ still exists. https://groups.google.com/forum/#!topic/v8-dev/WsIlpbaD4mo TEST= Run in debug mode, if you start a profile and don't stop it, this assert should fail: Fatal error in ../src/profiler/cpu-profiler.cc, line 414 Check failed: !is_profiling_. Review URL: https://codereview.chromium.org/1526253005 Cr-Commit-Position: refs/heads/master@{#32953} 

This commit fixes an occasional crash on shutdown when the profiler is still enabled. This seems like a good candidate for backporting as the fix is very straightforward, and it otherwise won't get into Node for quite a while.

This crash affects the appmetrics npm module. Appmetrics Issue 44

I'm not 100% sure whether I got the process right, if anything looks wrong then let me know.

@bnoordhuis Sorry about that, I've amended user.name on my fork, so I think the PR should update automatically. Is there anything else I should do to get it into Node 4? I noticed that you marked it as lts-watch-v4.x.

Thanks Gibson, CI is green. Landed in d5d301f, it'll be in the next v4.x release.
