Summary: spawn*() doesn't handle errors well

Initial Comment:
spawn*() routines are supposed to return the child's pid, 
but if an error occurs (such as bad parameters, etc.), it 
returns 127.  This "looks" like a valid pid, so the caller 
has no way of knowing if something when wrong.  
Throwing an exception would be much more 
informational (and python-esque).
