Reporting results as I get them...

This is for cross-compilation.

b111:

 run 1: hotspot/client/fastdebug Test results: passed: 320; failed: 11; error: 8
 run 2: hotspot/client/fastdebug Test results: passed: 321; failed: 10; error: 8

b110

 run 1: hotspot/client/release   Test results: passed: 325; failed: 14
 run 2: hotspot/client/release   Test results: passed: 325; failed: 14

Running with b111 (-conc:3 -agentvm) I'm left with 3 processes spinning
and introspecting those a little...

  $ jstack 4583

I do _not_ see this behaviour with b110.

And I repeated the exercise twice to avoid a sample size of 1...
