Right.  T-series threading is different than in competing CPUs.  Its 
resource scheduling seems to operate at a finer granularity, producing 
very high multi-threaded throughput.  The Sun/Oracle compilation 
toolchain and Solaris kernel are very well optimized for T-series. 
The T-4 sounds like it fixes the single-threaded performance issues 
that caused issues in the past and a 4 socket system will produce 
performance levels which used to require very large hardware.

The CPU should provide very good profit margins for Oracle.

It is questionable if outsiders would have the technical and financial 
resources needed to develop kernel support for newer T-series chips.
