[thinkanddone]

Feature Request

When we use command "gdb a.out" to debug a program, we can use "restart" command to redebug the program, this case just restart a.out process, don't restart gdb process.

But we use vscode debugger, click the Restart command when we debuging, it will restart gdb process.

Can we configure the vscode-debuger, make the gdb process not restart when restart debugger? bacause my a.out is very big, everytime restart gdb process will waste a lot of time.
