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.
