Description alarson 2015-11-04 13:33:20 MST 
Currently the virtual address for attached memory objects are all in MOM space.  This causes issues with the attachment limits in memory object memory (MOM) space.  POSIX also has a capability to mmap() a shared memory object at a user specified address, which is currently not supportable by Deos.
