Kelly was talking about separate processes running separate copies of 
jtreg for disjoint segments of the test suite. That is safe, and can use 
samevm/othervm as long as the tests themselves don't interfere with each 
other on shared system-wide resources such as port numbers.

For my part, I was talking about the basic JavaTest facility to run 
tests concurrently using multiple threads in the same JavaTest VM (using 
either the -concurrency command line option  or the "concurrency:" field 
in the GUI). That works for JCK, subject to the inherent 
test-interference rule -- for example it works for JCK compiler tests.   
jtreg does not support this level of concurrency.

Sorry for the confusion.
