spawnProcess always encodes its arguments in a very specific way 
and the receiving programs are not always compatible with that 
thing.

A Windows process does not take an array of args, but rather a 
single string command line. spawnProcess tries to turn the 
unix-style array into a single string that can then be turned 
back into arguments by the receiving program. But it makes a lot 
of assumptions in how that happens that just don't always match 
reality.
