Thanks for adding comments. I still think initHolder will be confusing 
to future maintainers and could benefit from a clear comment (above the 
static BOOL ...) to explain the parameters. One typo in the comment in " 
[thisProcessEnd] has no the inherit flag.".  The other functions are 
mostly clear now (thanks).

There are a few formatting oddities in 
Java_java_lang_ProcessImpl_create. Looks like a newline has crept into 
the if statement at L337. Then L358-364 is mis-aligned which makes it 
hard to tie the JNI ReleaseStringChars back to the JNI GetStringChars.

Thanks for replacing the fragile 10s in the tests. If I read performC 
(in both tests) correctly then the test will still pass after 5 minutes 
even if the JDK is broken - is that right? Just wonder if it would be 
better to just replace the for loop with while (true) and let the test 
harness timeout the test.

Otherwise I think this is good work and we are finally close to the 
finish line.
