Good benchmarks for testing GC performance/scalability

[Azeem Jiva]

Just an FYI, SPECjbb2012 is still under development.  Release date is 
later this year.  Even though both benchmarks are named "JBB" they are 
vastly different and are not comparable.  They both test business logic, 
albeit in slightly different ways.   SPECjbb2012 has an SLA requirement 
that SPECjbb2005 doesn't and the code for SPECjbb2012 is written from 
the ground up and shares nothing with SPECjbb2005.
