On Linux, pty.Open of github.com/creack/pty v1.1.24 passes the address
of a local variable to ioctl as a plain number, through a function
call. When Go moved the goroutine's stack in between, the kernel wrote
the pty's number to the old place, and pty.Open opened /dev/pts/0,
another terminal. secret rm wrote there, and the test read a terminal
no program had open, which never ends. Require the commit on the
library's main branch that passes a pointer; no release has it yet.
Both terminal tests now stop reading when their one-minute context
ends, and fail saying what was still waiting.
