Description:
I noticed that if a large entry (ie, an INSERT that contains a 20MB blob) shows up in the slow_log, it causes Workbench to grind to a halt for 30+ seconds.  Moving to a page of queries past the large one restores functionality to the tool.

How to repeat:
Trigger a slow_query that contains a lot of data -- like an INSERT with a large BLOB.

Suggested fix:
Truncate query output to 32KB or something similar -- the process viewer portion of the Administrator tool uses SHOW PROCESSLIST instead of SHOW FULL PROCESSLIST.  Similarly, showing less data in the slow query viewer should fix the problem.
