The problem appears to be XIO GSI driver passing an nbytes value larger than 
the buffer size passed to a write call (I pass in 1024, and 1049 is passed to 
my callback). GASS Server EZ is relying on the nbytes value to decide how 
large the buffer is for subsequent reads from the filesystem, and is thus 
corrupting memory.
