It doesn't always have to be that way, depending on the
nature of the command.  If it's the last thing the shell
has to do, then it can be exec'ed without a fork, which
leaves the gdb image running in the immediate child process.

Some shells do that automatically.  In any case, a Bourne
shell "exec" statement will do it, like "exec /.../gdb",
with whatever redirections etc.
