--- Comment #7 from Kurt Hindenburg <khindenburg at kde.org> ---
Git commit 25f8ebf9b67be936a60e2d45f69391378ce56788 by Kurt Hindenburg, on
behalf of Theodore Wang.
Committed on 10/09/2023 at 15:14.

Periodically check and update ProcessInfo::_name

Currently, there is an issue where 'exec [program]' results in tab
titles not being updated and not showing the process name as [program].
This is probably due to how 'exec' does not result in any change in
pid and simply replaces the current process image with a different one.

Due to a lack of pid changes, Session::updateSessionProcessInfo will not
call ProcessInfo::newInstance, thus not updating the ProcessInfo::_name.

This new change periodically checks and updates the _name of ProcessInfo
through ProcessInfo::readProcessName, which is called by
ProcessInfo::update.
