We're looking for developers writing multi-threaded Windows apps to try out Jinx, a new, hypervisor-based debugging tool. Jinx helps you find elusive concurrency bugs by running your application deterministically, looking for interleaving patterns that are most likely to cause problems.

Jinx works with native (C++) and managed code (C#, VB.net etc), and is currently supported on 64-bit Windows XP and Windows 7 platforms, and we require VMX (Intel) or SVM (AMD) virtualization extensions. Jinx can debug both 64-bit and 32-bit applications.

You can find more details at http://petravm.com, and can apply for the beta program at http://petravm.com/jinx/landing.php.
