A bunch of nits, otherwise looks good.

HeapSnapshotProgress:
start(totalWork)
worked(workDone)
done()
bool isCanceled()

> +    get statusBarItems()

why do you need this?

no trailing coma

No "get" prefixes in WebCore.

This is also a control interface -- when progress is reported it's possible to cancel job. So I made 'worked' to accept cancellation flag, and 'isCancelled' isn't needed.

Removed. ProfilesPanel required statusBarItems to be defined, I fixed this.

Fixed.

Fixed all such issues.
