A workaround to avoid duplicated debug sessions

On Qt Creator a user can open another debug session somehow even when there is an existing debug session already.
In such a case, no local veriables are displayed in the newer debug session, and it may confuse the user.
There should be a kind of fix to prevent users from running into sucn a situation.
For example :

• prevent two debug sessions at the same time
• displaying a proper message in the local variable debug view to indicate why they cannot be displayed.
• allowing two debug sessions to display properly the local variable

Thank you in advance for your consideration.
