Description of problem:
Keystrokes are handled asynchronously. ie: I press CTRL-A to select all messages and then quickly press delete it deletes just the one message that was hi-lighted prior to pressing CTRL-A.

Version-Release number of selected component (if applicable):
evolution-3.0.2-3.fc15.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Select a folder with a bunch of messages you want to purge. 
2. Click on a message.
3. Press CTRL-A
3. Press delete before the UI has updated
  
Actual results:
Only the message that was selected prior to the select all shortcut key is deleted.

Expected results:
All messages in the folder deleted, or more specifically, inputs are handled in the order in which they're given.
