This could be very dangerous: SHELL's value is supposed to be a file 
name, not a shell command, so switches (such as "/C") should not be
used.

I actually think that if "SET SHELL=%COMSPEC%" has weird side effects, 
such as CMD not exiting, it might be some bug that should be 
investigated.  The net effect of "SET SHELL=%COMSPEC%" on how the library 
function `system' works should be the same as not having SHELL set at 
all, and that definitely works, at least on some systems.
