Is vault thread-safe?

I don't see this addressed anywhere in the docs, and I assume that it isn't thread-safe, but I just wanted to check.

If you're using GHC, the library is thread-safe, because it uses only pure data structures (and unsafecoerce…). If you're using another compiler, then probably not.

Thanks! I had forgotten that it didn't run in IO. Too much STM lately.
