Seen on automation and misfiled under bug 1527502: https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=234448022&repo=mozilla-central&lineNumber=9909
fcntl is called with F_SETFD to set the close-on-exec flag (in a process that can't exec, but it doesn't know that) by FdWatcher::StartWatching, which has something to do with memory reporting.
I wasn't able to reproduce this locally; I'm guessing it's timing-sensitive, that normally the runnable that does this runs before sandbox startup, but it's possible for it to be delayed until after.
