ractor's threads. To avoid such data-race, some synchronization should
be used. Check include/ruby/thread_native.h and include/ruby/atomic.h.
On the Ractor mechanism, most of objects given by the method parameters
or the receiver are isolated by Ractor's boundary, it is easy to make
thread-safe code than usual thread-programming in general. For example,
we don't need to lock an array object to access the element of it.
With Ractors, all objects given as method parameters and the receiver (self)
are guaranteed to be from the current Ractor or to be shareable. As a
consequence, it is easier to make code ractor-safe than to make code generally
thread-safe. For example, we don't need to lock an array object to access the
element of it.
