Replying to [comment:9 vbraun]:
> It makes sense to have the "Unhandled SIGSEGV..." message at the end. I
don't think trying to get back from the debugger into the main program is
a good idea. Sage is currently in a signal handler after something bad
happened, there are no guarantees that anything is still working.
True, but what's your point? Your `execlp()` might also fail for this
reason. While `fork()` and `wait()` are basically pure system calls, so
much less probable to fail.
So I stand by my proposal to remove the `sleep(10)` kludge and replace it
by a `wait()`. Then you don't need to kill the parent process.
