[Pvfs2-developers] making alt-aio the default

[Phil Carns]

I'm going to commit a change to trunk to make pvfs2-genconfig 
automatically set TroveMethod to alt-aio.  I think we need to get some 
mileage on it and plan on it being the default in the future.  We can 
revert it if anyone objects or we see any problems.

I think the alt-aio method should be a pretty big performance win for 
the majority of setups these days.
