/* If the user presses Ctrl-c while the debugger is waiting
for an event, he expects the debugger to interrupt his program
and to get the prompt back. There are two possible situations:
- The debugger and the program do not share the console, in
which case the Ctrl-c event only reached the debugger.
In that case, the ctrl_c handler will take care of interrupting
the inferior. Note that this case is working starting with
Windows XP. For Windows 2000, Ctrl-C should be pressed in the
inferior console.
- The debugger and the program share the same console, in which
case both debugger and inferior will receive the Ctrl-c event.
In that case the ctrl_c handler will ignore the event, as the
Ctrl-c event generated inside the inferior will trigger the
expected debug event.
FIXME: brobecker/2008-05-20: If the inferior receives the
signal first and the delay until GDB receives that signal
is sufficiently long, GDB can sometimes receive the SIGINT
after we have unblocked the CTRL+C handler. This would
lead to the debugger stopping prematurely while handling
the new-thread event that comes with the handling of the SIGINT
inside the inferior, and then stop again immediately when
the user tries to resume the execution in the inferior.
This is a classic race that we should try to fix one day. */
