[Ironpython-users] [IronPython] unittest crash on mono

[Dino Viehland]

It looks like the current signal implementation won't work off of Windows.  There's a call to SetConsoleControlHandler that happens when the signal module gets imported - which is very windows specific and is going to fail on all other platforms.  

This can all be handled at runtime in a graceful way, but the calls to platform specific APIs need to be moved into non-inlinable methods.  In this case it seems like the 2 implementations are going to be pretty different given that everyone but windows has a reasonable signal function, so it might start to get to be a pain to keep both in the same module at the same time.  If someone wanted to get really adventurous they could add a platform attribute to PlatformID parameter to PythonModuleAttribute and have different implementations of modules for different platforms - then implementing the Unix signal implementation is probably pretty easy.
