Burkhardt,

Thanks for the patch.  Sean is working on integrating this into
the Orca source tree.

For the disk run percent change, I think there's a extra + in this line
near the end that can be removed.  Otherwise, it can match any number of
blocks of 32 characters of [A-Z0-9].

Your change:
disk_runp_((?:c\d+t\d+d\d+)|(?:c\d+d\d+)|(?:[ms]d\d+)|(?:c\d+t([A-Z0-9]{32})+d\d+))

New change:
disk_runp_((?:c\d+t\d+d\d+)|(?:c\d+d\d+)|(?:[ms]d\d+)|(?:c\d+t([A-Z0-9]{32})d\d+))

Does this look ok?

Best,
Blair
