Well, we need some workspace that won't go away when that happens.
I'd suggest that the OS and people's home directories be mounted on
a "permanent" partition with plenty of space for source code, say a
few tens of GB, and then there be a farm of data workspace that's
understood to be transient and can be reconfigured as needed for tests
like that.
