H - I am not familiar with flush(), will look into it. But an interesting note: I repeatedly and often start long running processes (one running right now: on about it's 14th hour), writing to open files, with few problems (on Mac OS X). Although of course I can't look at the results until the file closes...just have to hope it's right! LOL
B - You are right about Sqlite, I'm a big fan (moved over from MySQL a few years ago). But the structure of the data for this project is much better suited to a 'flat file' format. Again, not that I am having problems, just thought I'd raise the topic. BTW PyCON is in Chicago this year (where I am), maybe I'll meet some of you there?
