Well, Ruby's String certainly has no synchronizations built in with the
library you want to integrate so how will you ensure that there is proper
synchronization?  So far I have only seen that you want to share the memory
of a Ruby string's byte array with some third party library which will then
write to the memory from threads not controlled by Ruby.  You said you need
"only one blocking syncronization call from Ruby to start working with the
string" - but what do you do afterwards, i.e. while the processing is under
way and "the string changes should be immediately visible in Ruby"?

Cheers
