Looking at the implementation of disable multi-threading it seems like it destroys the thread-pool. My understanding is that this will also free the allocators in the thread local cache (i.e. the IR would break). A thread local cache, for this use case, only makes sense if the thread pool is alive during the entire lifetime of the mlir context.
