Reading your comment the irony occurs to me that the best solution to "compile once" has been real VMs. Not Java VMs, but full god damned fucking virtual machines running the OS and environment you determine should run in them.
You've still got to provision those, but, well, they're individual and isolated and tend not to go hammering into one another. Other than consuming all available system resources.
Oddly: IBM got this right with VM ... 40 years ago?
