Thanks for that patch - I'll watch this with great interest.
Is there a problem if dynamic libraries invoke dlopen/dlclose they also need to call the sync function - correct?
I'm asking because we've developed a Common Lisp implementation that interoperates with C++ and it uses exception handling to unwind the stack (https://github.com/clasp-developers/clasp.git). We hit this global lock in unwinding problem a lot - it causes us a lot of grief.
