func IsNoChildProcesses

func IsNoChildProcesses(err error) bool

exec.Command().Run() and its derivatives sometimes return "wait: no child processes" or "waitid: no child processes" even for successful runs. It's a race condition between the Start() + Wait() calls and the actual underlying command execution. The shorter the execution time, the higher are the chances to get this error.
