* spintrcritical01/init.c, spintrcritical06/init.c,
spintrcritical08/init.c, spintrcritical13/init.c: Lower microseconds
per tick so tests run quicker and more reliably hit the intended
critical section.
* spintrcritical01/init.c, spintrcritical06/init.c,
spintrcritical08/init.c, spintrcritical09/init.c: Perform some
cleanup and make the tests more similar.
* spintrcritical06/init.c: Add comment to indicate test is not finished
and known to not hit the case.
* Makefile.am, configure.ac: Add a couple more interrupt critical
section tests.
* spintrcritical08/.cvsignore, spintrcritical08/Makefile.am,
spintrcritical08/init.c, spintrcritical08/spintrcritical08.doc,
spintrcritical08/spintrcritical08.scn, spintrcritical09/.cvsignore,
spintrcritical09/Makefile.am, spintrcritical09/init.c,
spintrcritical09/spintrcritical09.doc,
spintrcritical09/spintrcritical09.scn: New files.
