`spawnProcess`: The optional arguments stdin, stdout and stderr may be 
used to assign arbitrary std.stdio.File objects as the standard input, 
output and error streams, respectively, of the child process. The former 
must be opened for reading, while the latter two must be opened for 
writing.

For POSIX, seems like you could pass `File("/dev/null", "r")` for stdin 
and `File("/dev/null", "w")`.  On Windows I believe you can use `File
("nul")` for the same effect.
