Is that technically feasible? The $thread variable must be set before the call 
to bpstat_stop_status, otherwise you can't use $thread in breakpoint 
condition. Well, you can, but when evaluating breakpoint condition you'll use 
the old value of $thread, not the number of the thread where we've stopped.

Unless cli-script.c is somehow invoked from handle_inferior_event.
