what about Azul's Zing JVM?

[Li Li]

hi everybody,
    I read an article today about Azul's Zing JVM. It is said that this jvm
is pauseless.
    In my application, our machine is about 48GB and about 25GB memory is
given to jvm(by -Xmx). But it will occasionally pause 1-2 seconds.
    So when I saw this, I want to know whether it's so good as they say.
And I googled and found a related question in stackoverflow:
http://stackoverflow.com/questions/4491260/explanation-of-azuls-pauseless-garbage-collector
    after reading, I am still confusing. Anyone would give more detail
explanations about it? thanks
