> And I thought we agreed there's no point in trying to fix that, because
since they're all running as the same user, they can do things like read the
certs used to encrypt the other app's traffic, read the other app's memory, and
all other nasty things.
My thought was we can still make some gain by leveraging process-level
isolation, even though they are running as the same user. Apps won't
automatically read each other's memory, right? Being able to read others' SSL
certs doesn't mean one can decrypt traffic. Each session is encrypted using a
freshly generated session key.
> It's bad to use stdin for this. For one, it has weird semantics on
Windows. And for second, stdout and stdin are generally considered to belong to
the application, and thus Spark shouldn't really touch them if possible.
That's a valid point. Thanks for bringing it up. I'm not familiar with
Windows. Can you expand a little?
