Your citation refers to a proprietary program that was presented at EuroLLVM - their changes are not upstream.  They are running multiple MCJIT instances in parallel, but they are completely independent - different modules and different LLVMContexts, and so passes are completely independent (unless they do something silly like have some mutable static variables).  This is a completely unrelated problem.
