Separate to your actual problem: Is there a reason for splitting like
that, rather than simply using a list of separate arguments? That
would be a lot safer and easier; no going through the hassles of
quoting and splitting.

Your exact problem is likely to be due to unclosed files. I don't know
enough about .communicate() to know whether it closes everything
immediately or not, but it looks like you're progressively opening
more and more and more pipes.
