This should happen automatically under the hood as libc processes
signals in ordinary I/O signal handlers in the entrypoint.
Are you able to run the scenario under linux and inspect the
processing of both threads via GDB? I fear that I cannot help with
specifics of OpenVPN, but may guide with more details about the
blocking situation. It may be interesting to know if any network
packets reach the OpenVPN code.
