Thread safety in lazy deserialization mode

Since all the deserialized objects are created on demand, can I access (read) a single FlatSharp object from multiple threads?

Yes. Lazy is thread safe, but you may experience some issues if you are using WriteThrough to modify the underlying buffer. There are two types of things that could crop up:

1. Inconsistent reads. Thread A writes a new value, thread B observes the old value. Normal stuff.
2. Partial writes. Value-type structs support writethough, but the entire struct is written back. For large structs, the write will not be atomic, so you may observe some issues.

The other thing to consider is if you're wrapping an unmanaged segment of memory with Memory before deserializing, it's up to you to ensure that everyone is done using that object before releasing the underlying memory.

Nice, as I expected. Thank you!
