As another example: I tried to get some R code distributed with MPI using a package that claims to do this. If I remember correctly, the package would generate and execute a shell script to spin up subprocesses. Then it would shuttle code (including huge matrices serialized to ASCII) over a socket, to be eval()'d on the other side. The secret codeword "kreab" would terminate the connection, so this could appear nowhere in the code sent over the socket. This is clownshoes software quality. And it's used for important scientific research.
