[xcpu] xcpu and CUDA

[Eric Van Hensbergen]

And while I am at it, anyone use xcpu or xcpu2 with CUDA yet.  When  
using xcpu2 I'm getting:

% xrx 9.3.61.111 /bin/bash
/deviceQuery
dev count = 1
Querying device = 0
cudaSafeCall() Runtime API error in file <deviceQuery.cu>, line 61 :  
feature is not yet implemented.

(and it runs fine when run manually on the device)
Not sure what in the namespace is messing with it, debugging now, but  
figured I'd post here in case someone has already ran into it.
