logkeys doesn't log everything sent if keys are sent in fast bursts (by hardware)

```
What steps will reproduce the problem?
1. Program a USB device ( a Teensy++2.0 from www.pjrc.com) that emulates a USB
keyboard, but which doesn't require a human to actually press the keys.
2. Plug in the USB device, and have it send a fast burst of data via the
keyboard input.
3. The data is not logged by logkeys, but is detected by the active window.

What is the expected output?
All of the data sent via the keyboard input should be captured by logkeys, even
if it is sent in fast bursts.

What do you see instead?
I see the human entered text before and after where the machine-generated text
should appear, but not the machine-generated burst of characters

What version of the product are you using (`logkeys --help`)?
0.1.0

On what operating system?
Ubuntu 11.04

The report names no source files or tests. Reproduce the failure with the Teensy keyboard device on Ubuntu and inspect the keyboard input-event handling; done means every character from a fast burst is captured by logkeys, matching the active window.
