Related to rscarson/rustyscript#228

Multiple users are reporting a segfault when instantiating JsRuntime instances on multiple threads

From one user's report:

Debugging showed that internally the two runtimes used the same memory map for their v8 engines, causing segfault. Fixed it via creating snapshots of the runtimes, which made them reference their own memory map not a global one.

Issue was reported on some Linux hosts, I cannot reproduce it on my end
