RFR 9: [TESTBUG] 8078582: java/lang/Runtime/exec/LotsOfOutput.java fails intermittently with Process consumes memory

[Roger Riggs]

Please review this update to a test to make it resilient to small 
allocations
that may bump the total memory.  The test will also collect more data if 
it fails again.
