[Swift-devel] Planning next set of Swift features and releases

[Ian Foster]

The GPFS issue was quite fundamental at the time--IBM would not  
guarantee that a VM node running GPFS would not corrupt GPFS. They got  
past the issue eventually, I don't know how.

Anyway, we should keep pushing people on this. In the meantime, EC2  
and Nimbus are good targets.
