[PATCH 1/1 V5] gdb : Signal to pstack/gdb kills the attached process.

[Pedro Alves]

Hi.

Just wanted to let you know that I've read all the discussion around this until this
email I'm replying to, and started thinking about it a bit.  Unfortunately this is one of
those areas in GDB where the right change is rarely immediately obvious (to me).

Some questions:

 - If you ctrl-c to abort the attach, do we really abort the 
   attach properly?  Or do we stay attached in some half broken state?

 - Below you mention pstack, where can we find it?  And you mention
   that ctrl-c is pressed while that is printing a stack.  I'm assuming
   that's a backtrace command.  I'm confused in that case, as if that is
   so, then we should already be past the initial attach.  The question
   would then becomes, shouldn't gdb have the terminal at that point?
   How come it does not?

I'm wondering whether Baris's patch to eliminate the inferior
continuations would help with this, as it probably makes the attaching
sequence synchronous.  I should probably look at that one.
