bug#12425: 24.2.50; gud-mi failing with threads 'Cannot get thread event

Hi Emacs buggers,

When running my employers programms in the new emacs24 gdb behaves bad
because of the threadding model. Its a per request worker thread model;
I wasn't able to reproduce the problem with citadels threadded
components.

I tried to compile from latest git, run with '-q' problem persists.

since this used to work with emacs-GUD in emacs 23 without troubles, I
retried using other gdb-mi frontends: kdevelop; worked without problems.

i've straced GDB to show the IO's between emacs and GDB <see attachment>
