    hmm...you are now the second person to report that creating the tmp files does not work
on OS X. i don't know why that doesn't work. the file creation is done from java, is there
any magic required there? i can't debug OS X error myself at the moment. all i can do on that
front is add sanity checks for better error reporting.
    
    the included triangle enumeration is kinda odd, even if it runs the output is empty; Ive
already checked the implementation yesterday and it appears equal to the java counterpart.
will give it another go.
    
    the plan execution is one of the more fragile parts. generally, when the process exits
with an error it is noticed. but if for example something is missing (like the call to execute)
things just get stuck. this is due to the fact that information is only ever sent to java,
but never received, a complete one-way street. since accumulators nor actions were supposed
to be implemented anytime soon this seemed appropriate, but it seems that requires a change
already. some timeouts could be useful as well.
    
    @fhueske Thanks for trying it out!
