Hi folks,
I've found it is possible to Eshell in the middle of a command. Here's a
recipe:
1. Emacs -Q
2. M-x eshell
3. In Eshell:
$ for x in 1 2 3 4 5 { echo hello ; sleep 2 } > #<buffer test>
4. While the above command is running, C-x b test
5. C-x b *eshell*
Observe that the loop will never finish and the Eshell buffer becomes
unresponsive. For example, pressing RET does nothing. Pressing C-c C-c
will terminate the command, but Eshell no longer accepts new commands.
Please let me know if I can provide additional information.
Thanks!
In GNU Emacs 30.0.60

Tricky! But thankfully it was an easy fix. We just needed to make sure
that when cleaning up in a timer after 'eshell-sentinel', we always do
it from the Eshell buffer.
Fixed on both the master branch and the release branch, with a
regression test.

Thanks. But in the future, please install bugfix changes for Emacs 30
on the release branch; they will be merged to master when one of us
does such merges (which happens every few days as a matter of
routine). The "install-on-master-then-cherry-pick" method should be
reserved for the rare cases where a change is installed on master
either by mistake or because the author believed it was not
appropriate for the release branch.

Sorry about that. I'd accidentally merged to master first, so had to fix
things up by cherry-picking.
