Apologies for the late response, I was traveling most of yesterday.

I think we should keep the behavior the same on all platforms. If such a 
change is to occur, it should happen at the same time on Windows and 
Unix-like systems. Platform-dependent ifdefs should be used to overcome 
platform-specific differences (e.g. the location of the shell), rather 
than give one platform entirely different functionality - otherwise we 
introduce needless confusion when someone accustomed to Linux tries to 
use an exec migration on Windows and it doesn't work the same way at all.
