I have 8GB Ram and only 10GB virtual on this Win7, so it looks like the
<forkCount>2C was too much for that poor Notebook. It caused malloc
failures (in the C1 and C2 compiler threads of the JVM).

This machine uses HT and therefore Java sees 8 cores, so 16 Forks is rather heavy. 
Using forkCount=8 finishes all ITs with no failures or crashes,

(but the unit test failure still happen)
