I use screen in a docker container on Home Assistant OS on a x86 machine.

```
# uname -a
Linux core-ssh 6.1.25 #1 SMP PREEMPT_DYNAMIC Tue Apr 25 11:50:31 UTC 2023 x86_64 Linux

# screen -v
Screen version 4.09.00 (GNU) 30-Jan-22

# cat /etc/os-release
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.17.3
PRETTY_NAME="Alpine Linux v3.17"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"
```

Just running `screen -v` is very slow as well.

Very slow means tens of seconds or minutes - prior to the latest update of the docker container, this took about 1 second max.

```
strace -f -o screen.log screen -v
```

The screen.log shows many lines similar to the following:

```
22942 poll([{fd=3, events=0}, {fd=4, events=0}, {fd=5, events=0}, {fd=6, events=0}, {fd=7, events=0}, {fd=8, events=0}, {fd=9, events=0}, {fd=10, events=0}, {fd=11, events=0}, {fd=12, events=0}, {fd=13, events=0}, {fd=14, events=0}, {fd=15, events=0}, {fd=16, events=0}, {fd=17, events=0}, {fd=18, events=0}, {fd=19, events=0}, {fd=20, events=0}, {fd=21, events=0}, {fd=22, events=0}, {fd=23, events=0}, {fd=24, events=0}, {fd=25, events=0}, {fd=26, events=0}, {fd=27, events=0}, {fd=28, events=0}, {fd=29, events=0}, {fd=30, events=0}, {fd=31, events=0}, {fd=32, events=0}, {fd=33, events=0}, {fd=34, events=0}, ...], 1024, 0) = 1024 ([{fd=3, revents=POLLNVAL}, {fd=4, revents=POLLNVAL}, {fd=5, revents=POLLNVAL}, {fd=6, revents=POLLNVAL}, {fd=7, revents=POLLNVAL}, {fd=8, revents=POLLNVAL}, {fd=9, revents=POLLNVAL}, {fd=10, revents=POLLNVAL}, {fd=11, revents=POLLNVAL}, {fd=12, revents=POLLNVAL}, {fd=13, revents=POLLNVAL}, {fd=14, revents=POLLNVAL}, {fd=15, revents=POLLNVAL}, {fd=16, revents=POLLNVAL}, {fd=17, revents=POLLNVAL}, {fd=18, revents=POLLNVAL}, {fd=19, revents=POLLNVAL}, {fd=20, revents=POLLNVAL}, {fd=21, revents=POLLNVAL}, {fd=22, revents=POLLNVAL}, {fd=23, revents=POLLNVAL}, {fd=24, revents=POLLNVAL}, {fd=25, revents=POLLNVAL}, {fd=26, revents=POLLNVAL}, {fd=27, revents=POLLNVAL}, {fd=28, revents=POLLNVAL}, {fd=29, revents=POLLNVAL}, {fd=30, revents=POLLNVAL}, {fd=31, revents=POLLNVAL}, {fd=32, revents=POLLNVAL}, {fd=33, revents=POLLNVAL}, {fd=34, revents=POLLNVAL}, ...])
```


I notice that the value for 'fd' is continuously increasing.  On line 3196 of the log I get:

```
