* lin-lwp.c: Prevent thread starvation by using a monte carlo
method to choose which of several event threads to handle next.
(stop_wait_callback): Defer pushback of breakpoint events until
later; add SIGTRAP events to the queue of unhandled events.
Keep calling waitpid until SIGSTOP retrieved. If more than one
non-SIGSTOP event is retrieved, push them back onto the process
queue using kill.
(count_events_callback, select_singlestep_lwp_callback,
select_event_lwp_callback, cancel_breakpoints_callback,
select_event_lwp): New functions. Implement monte carlo method
for selecting which of several SIGTRAP threads to handle next.
Push back the breakpoint event for all threads other than the
selected one.
(lin_lwp_wait): Call select_event_lwp to decide which of several
sigtrapped lwps to handle next.
(resume_callback): Disable code that attempts to handle
step_resume breakpoints. Let core gdb handle this.
