Yes.
Right now I have nothing to add ;) I'll try to think more, but every
proposal looks as "obviously makes sense" to me. However, I do not
know what is useful for GDB.
Only one note,
> * PTRACE_ATTACH_NOSTOP
How about PTRACE_DETACH_NOSTOP? Like PTRACE_DETACH, but doesn't
require the stopped tracee.
I was really amazed when I looked into strace sources. The code
which handles detach is soooooo complicated (and I do not blame
strace). But, again, I do not know if this makes sense for GDB.
Oleg.
