Bug Description

The trace event patch I wrote during karmic gave readahead events for each open() syscall, along with the filename.

It turns out that exec() is kinda useful too. I've updated the patch to add these, and for completeness uselib() as well.

Please apply in an SRU so we can ship better readahead!
