is a bit trickier. When doing an attach, the kernel stops the
debuggee with a SIGSTOP. On newer GNU/Linux kernels (>= 2.5.61)
the handling of SIGSTOP for a ptraced process has changed. Earlier
versions of the kernel would ignore these SIGSTOPs, while now
SIGSTOP is treated like any other signal, i.e. it is not muffled.
If the gdb user does a 'continue' after the 'attach', gdb passes
the global variable stop_signal (which stores the signal from the
attach, SIGSTOP) to the ptrace(PTRACE_CONT,...) call. This is
problematic, because the kernel doesn't ignore such SIGSTOP
now. I.e. it is reported back to gdb, which in turn presents it
back to the user.
To avoid the problem, we use STOP_QUIETLY_NO_SIGSTOP, which allows
gdb to clear the value of stop_signal after the attach, so that it
is not passed back down to the kernel. */

The "*" gets expanded by the shell into a list of files.
While this is a nice feature, it turns out to interact badly
with some of the catch-fork/catch-exec features we have added.
In particular, if the shell does any fork/exec's before
the exec of the target program, that can confuse GDB.
To disable this feature, set STARTUP_WITH_SHELL to 0.
To enable this feature, set STARTUP_WITH_SHELL to 1.
The catch-exec traps expected during start-up will
be 1 if target is not started up with a shell, 2 if it is.
