The number of test iterations can be specified so that the test
does not continue forever without manual intervention.
This enables better use of mtest via scripts.

Hi,
I actually work on a patch series to improve|rewrite the memtest command.
This will add a iteration argument, too.
I will try to find some time this weekend to make it done.
Regards
Alexander Aring

What's with [pattern]?
It's only available in MTEST_ALTERNATIVE.
