[Mono-dev] Mono JIT Init for two different versions

[Rodrigo Kumpera]

Loading two runtimes in the same process is not something mono was designed
to. You might encounter all
sort of issues when doing so.
You'll have to call all mono functions using function pointers and hope it
works as expected.

Multiple GCs in the same process will be racy and you might end up getting
all sort of crash deadlocks.

Good luck.
