Yes, RP's previous patch does reduce the Noexec messages a lot. However there
remains one problem. Current stamp file check also calculates the stamp of tasks
depended on. If those stamps are newer or not exist, the check return False to
indicate mismatched stamp.

In 'noexec' case, some 'noexec' tasks happen to have some dependent tasks
skipped which thus don't generate stamp files. This makes the check always
failed for those 'noexec' tasks and thus you always observe the Noexec messages.

I have a patch to fix that, and will send out soon. :-)

Thanks
Kevin
