There is no `Drop` implemented for `Child`, so if it goes out of scope in Rust-land and gets deallocated, the child process will continue to exist and execute. If users want a guarantee that the process has finished running and exited they must manually use `kill`, `wait`, or `wait_with_output`. Fixes rust-lang#31289.

AFAIK the "Safety" heading is for memory safety and memory safety only. Also AFAIK a child process terminating later than expected is not a memory safety hazard. If I'm correct about both things, this heading should be renamed.

@rkruppe: Was wondering about that myself. Any suggestions?

re-queueing travis. The structure and format look right to me, but r? @alexcrichton because I don't know enough about the accuracy here. |

Dropis not implemented forChild, so if it goes out of scope in Rust-land and gets deallocated the child process will continue to exist and execute. If users want a guarantee that the process has finished running and exited they must manually usekill,wait, orwait_with_output.Fixes #31289.
