+Subject: [PATCH] mieq: Bump default queue size to 512
+
+Based on some bugzilla scraping just now.  Of xserver bugs with
+attachments, the distribution looks 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.
