in #177, it reverted #167, however, the revert seems not sufficient. we uses buildkite agent which depends on this pty package's v1.1.21. However, we are still seeing
fork/exec... operation not permitted
when PTY is enabled.
Note that v1.1.21 does help in that the occurrence of this bug is lower than v1.1.20. However, it just still happens at a lower rate.
Use the helper `pty.Start()` instead of handling ourselves the tty and associated ptty. Wait for the finalization of the command just with the copy, to avoid a separate goroutine in an attempt to avoid the hangs we are seeing in CI.
Downgrade to pty 1.1.19, that seems to solve some kind of race condition creack/pty#196 that could be producing
the hangs.
