> Apps won't automatically read each other's memory, right?
The point is not that they will automatically do it, the point is that they
can.
> Being able to read others' SSL certs doesn't mean one can decrypt traffic.
It does because the session key is encrypted using the cert's private key.

We've had issues in the past with pyspark and Scala code that messed with
stdin.
Since there's a trivial option that doesn't involve using stdin and does
not have any drawback security-wise, I don't understand what's your reluctance
in using it.
