The .astlog file seems to be cumulative since program restart. It also seems to interleave log messages for all concurrent downloads. I've taken to restarting anystream intermittently as I was seeing 20+mb astlogs. Any chance we can get an option (or just a change) to truncate the log each time the log is written? This would be simpler if you separated out per-provider astlogs. Such logs would be smaller, cleaner, and would actually match the file they were associated with.
