Suppress `warning: execute_coproc: coproc [40158:xxx] still exists`

[Peng Yu]

Hi,

I see the following warning. Is there a way to suppress it? Thanks.

./main2.sh: line 11: warning: execute_coproc: coproc [40175:name1] still exists

$ cat ./main2.sh
#!/usr/bin/env bash

coproc name1 {
seq 3
}
exec {fd1}<&"${name1[0]}"

coproc name2 {
seq 4 6
}
exec {fd2}<&"${name2[0]}"

sleep 1
while IFS=$'\t' read -r -u "$fd1" line; do
    builtin printf '%s\n' "$line"
done

while IFS=$'\t' read -r -u "$fd2" line; do
    builtin printf '%s\n' "$line"
done

$  ./main2.sh
./main2.sh: line 11: warning: execute_coproc: coproc [40175:name1] still exists
