On Windows, the handling of SIGINT (aka Ctrl+C for a DOS prompt) is done in a different thread than the running thread. Which means that the current runtime cannot handle it properly without failing, since it throws an exception in the wrong thread. This problem is even more visible in a multithreaded application.

I've posted a question on the Microsoft newsgroups and here is the discussion thread. The interesting part of this is a reference to another discussion thread where they propose a solution.

This needs to be investigated.
