<div><br></div><div><br></div><div>Also, there were no performance regressions detected on Linux multithreaded test run for the change in implementation of the multi-core testing. What I changed was implementing the worker threads via Python's multiprocessing.Pool class instead of using the threading module's threads. All the MacOSX threads were locked on the Python global interpreter lock. Not entirely sure what the diff was that prevented that in Linux and FreeBSD, but no matter. The Pool implementation is slightly cleaner anyway.</div>

I'm looking at adding a new test declaration that lists a test as load sensitive (@load_sensitive_test), and somehow allowing that to fail in the multithreaded pass without failing the test run. Then, run all the load-sensitive tests in a follow-up single-threaded pass if they failed under load. Then, only mark them as failed if they fail under the single-threaded pass. I'll have more to say on that when I get some time behind it. If we do something like that, it should eliminate the tests that are hard to simplify and work under load, without forcing us to run all tests in a *much longer* single-threaded manner.<span><font color="#888888"><br clear="all">
