I'm interested in the issue with using env, but I find you explanation a but hard to follow. What are some situations that lead to the problems you are describing. I'm currently using env in some gems and if there is a strong argument against it, I don't mind switching it.

If you simply change a String's content from some other thread no piece of
Ruby code will be aware of this so nothing can really do something with
that changed content in Ruby land.  You need a method call, either from
Ruby side (i.e. when it needs the data) or from the extension side (i.e.
after every update).  If you do it from the extension side things get more
complicated since you need to pass in a Ruby object as callback plus ensure
that the calling thread is a Ruby interpreter thread.

Btw, what are you trying to create here?

Cheers

robert
