[jboss-dev] configs are broken

[Ales Justin]

As we don't vote or go 'with it w/o reason' (Adrian's rules) ;-)
I'll explain a bit my options:

>  - (1) + proper strong ref on this: 
> http://www.jboss.com/index.html?module=bb&op=viewtopic&t=145039

We keep the most used one's via strong ref on VFSInitializer,
but let other temps be GCed asap.

>  - (4) with limit long enough to do common apps deployment triggered 
> upon this cache

We make the timed limit long enough that most of apps make advantage of 
this vfs cache,
once initialization period is over, flush it all.
