Based on some bugzilla scraping I did around November 2012. Of xserver bugs in Red Hat bugzilla with an EQ size message in the log, the distribution looked like:
String | Matches ------------------------------------- Increasing EQ size to 512 | 460 Increasing EQ size to 1024 | 52 Increasing EQ size to 2048 | 6 Increasing EQ size to 4096 | 0 Most of the "512" ones appear to be mostly harmless, some relatively expensive path in either rendering or resource destruction simply taking too long due to external pressures like paging or CPU contention. So let's raise the initial queue size, both to reduce the number of spurious abrt reports and to drop fewer events in all but the most pathological cases.
