[concurrency-interest] Direct Byte Buffer memory visibility

Hi,

just musing: is it reasonable to assume that all rules for operations
on object fields and arrays also extend to direct byte buffers?
I.e. is the visibility guaranteed when I construct a happens-before
relationship between the modification and the reading of buffer
contents?
I assume the intrinsification happens-before reordering so the stuff
looks the same to the optimizer?

Thanks
Matthias
