Change information
Commit message:
os/exec: document that Cmd.Wait must not be called concurrently
Clarify in the Wait documentation that it must not be called
concurrently from multiple goroutines. Also note that a custom
Cmd.Cancel function should not call Wait because Cancel may be
invoked by watchCtx in a separate goroutine.
Fixes #78046
