Hi GNU Team,
I found that program called by timeout cannot interact with tty stdin
when timeout is called by exec().
A simplest example is `timeout 10 timeout 5 cat`. cat cannot read input
from tty stdin.
I also tried to run `timeout 5 cat` in other programs by exec(), and
all of them cannot read tty stdin. For example,
import subprocess
subprocess.run(f"timeout 5 cat", shell=True)
timeout has a --foreground option to support this case,
with the caveat that if the program forks children,
they'll not be timed out.
See https://www.gnu.org/software/coreutils/timeout for details.
cheers,
Pádraig
