So either it is
- a performance test - then it needs to track the time per platform, the limit should be tight and it must not run in parallel with other parts of the testsuite, IIRC perf lab dept. should take care of it
- or it just checks whether it completes at all - and then it needs no limit at all as there is already a JTREG testcase limit
