[PATCHSET] dsmark fixes & cleanups

[Thomas Graf <tgraf@xxxxxxx>]

Dave,

The following patchset fixes various smallish bugs in dsmark
and does a general cleanup. The lower the patch number,
the less intrusive and more serious the bug is.

Patches tested using tc-testsuite (see below) and some
manual testing.
