Bob,

it is not possible with the current GDB. All of the commands are executed in the single
thread GDB has, in the order they were received.

It is possible, in theory, that somebody will require GDB in node.js, or introduce asynchronous
operation using boost.asio or similar, but that's quite unlikely scenario.
