With this patch print IPC no longer requires the child process to create files. Instead files are opened by the parent and a file descriptor is sent to the child. This will allow us to sandbox child processes more aggressively. MozReview-Commit-ID: GQWTYLV01kj --HG-- extra : rebase_source : 9b91e9b01708d73915a49684c2cec96457650e45
