v3.10.0 doesn't have the full fix for reading in while loops hanging

[andrewimeson]

Continuation of #1099. For some reason, despite the fix and new tests added in f3c9101 passing, the issue wasn't fixed until aecfbc3. Could we get a release soon that has that commit? Thanks for all your work on this tool!

This is the script that still hangs on all of these in v3.10.0. It might be good to figure out why the tests didn't actually surface the failure.

#!/usr/bin/env gosh
set -x

echo a > f; while read a; do echo $a; done < f

echo "hi pipe" | while read -r line; do
    echo "$line"
done

while read a; do echo $a; done < <(echo x)

exit 0

echo "hi file" > hi.txt

while read -r line; do
    echo "$line"
done < hi.txt


while read -r line; do
    echo "$line"
done < <(echo "hi file substitution")

echo done

I'm not particularly surprised that aecfbc3 fixed more edge cases, as it removed a significant amount of complexity coming from a third party library whose behavior I don't fully understand.

Is there a reason why go-task can't use our library at master until we are ready for a release? I will do a release soon, probably in the next few weeks, but I'd rather not be rushed into a release right now. The commit above is also a bit too risky for a backport.
