That's impossible. The whole point of releasing the GIL is to say "I hereby promise I won't be interpreting any Python code until I reacquire the lock". If you could do that from Python code itself, you would create a singularity that will suck in the solar system. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
