Ok, seems fine to confine it to just this script with a comment about the
reason.

Given the current code relies on posix mode being off, turning it off
explicitly shouldn't affect other behavior, especially since the change is
confined to just the spark-class subshell.

Are there downsides to turning off posix mode?
It seems reasonable if it makes this case work and doesn't affect other
behavior.
